    Title: Method and device for hatching hatching eggs and guiding newly hatched chicks
    The present invention relates to a method for hatching hatching eggs and guiding newly hatched chicks, called day-old chicks, wherein such hatching eggs are placed in hatching trays with wall parts that enclose at least a single bottom. Such a method and device are generally known and have been used for years.
    More in particular, methods are known in which special measures are applied. Some of them will be mentioned in detail below.
    The present invention further relates to a device for hatching hatching eggs and guiding newly hatched chicks, the device being provided with, inter alia, hatching trays, detectors, and a control device.
    Devices of such a general type are already used in the art for hatching eggs, for example but not exclusively chicken eggs.
    In WO2007110861 it is described how so-called troughs are arranged in such hatching troughs, functioning as a food reservoir and placed in the walking space of chickens that have just broken out of the egg. An application has been chosen for the preservation that is expected to stimulate eating well before and after the hatching of the chicks.
    In EP2560482 specifically mentioned food reservoirs or troughs are arranged against wall parts of a hopper, in which food is present, mainly as a granulate. By means of an outflow opening on the underside, i.e. as a result of its own weight, the granulate sinks via the outflow opening to and into a gutter section. From there and from there, the chicks will then pick up the granulate.
    It is known from NL1027818 to package the food in the form of a mat and to apply it to bottom parts of a said hopper.
    Neither extensive yields and results nor further improvements are known from these publications.
    In the hatching egg technology, attempts have been made for a long time to bring the different hatching times closer together, which is referred to as reducing the hatch window. More specifically, this is achieved by adjusting the climate in the incubator, for example by adjusting the temperature, or the concentrations of carbon dioxide and water vapor. It has been achieved that the hatching time, from first to last chick, has indeed been somewhat reduced, from roughly 24 hours to less than 20 hours, sometimes even 16 hours.
    For example, such a method is described in WO2008084379. More in particular, it is suitable for following growth processes, and actively controlling these growth processes based on the information obtained about them. As already mentioned above, the direct growth process in the egg is thereby influenced.
    Further research has shown that for a situation that approaches a natural environment, the chicks thrive best.
    Unlike active intervention in such a life process according to WO2008084379, improving and optimizing the living conditions of day-old chicks is a problem that requires a solution.
    It has been found that the living conditions can be improved and hence the yields can be increased by applying the method according to the present invention.
    The invention is characterized by the features of claim 1.
    According to an aspect of the invention, the hatching is followed well in advance of the expected start and then, roughly from the first moment of hatching and on the basis of the further results of monitoring or monitoring, the chicks are closely monitored.
    The chicks benefit greatly from the possibility of eating after hatching, in particular after a few hours have passed.
    It has been found that this method is very suitable for obtaining day-old chicks that go through a further prosperous growing.
    In particular, hatching trays are provided with sensors and with food mats, wherein a holding cycle is suitably applied depending on the sensors for the hatched chick. For this purpose, defined periods are used during hatching.
    According to a further measure of the present invention, after a certain period of time the adhesion is stopped, in particular following the measurement of a maximum in the water vapor pressure, on average for chicken eggs after more than 2 days, it being generally known that approximately 20% of the chicks will break out of the egg. Because these chicks are the least strong, extra efforts for these animals must be avoided. It has been found that on the one hand, mortality among these still to be hatched chickens is suitably limited by stopping the handle just then, while on the other hand the stronger chicks, now broken from the egg, experience no disadvantage of stopping.
    It is precisely there that the present invention provides for an improvement in the living environment, similar to that of chicks in natural living conditions.
    It has been established that further improvement of the living environment for such day-old chicks is necessary in order to increase the yields, namely the meat yield where broilers or broilers or broilers are concerned, or laying frequency with regard to laying hens.
    Furthermore, an aspect of the invention provides a device characterized by the features of claim 8. The device can be configured, for example, to perform a method according to the invention.
    Suitably the device according to the present invention comprises - hatching trays with wall parts enclosing at least a single bottom in which such hatching eggs are placed, - detectors arranged near the hatching trays for monitoring the hatching of hatching eggs, with hatching signals for each such egg light sources for controlled exposure of the chickens in said hatching trays are obtained, - food compartments accessible to the chick after hatching, arranged in the at least some bottom, and - a control device for processing said signals and for controlling feeding and lighting the chicks.
    In further exemplary embodiments, the device has one or more of the following features: that the detectors are mounted on the wall parts of the hatches; that the detectors comprise at least sensors of a single type, for example infrared sensors, for the targeted recording of movements; that the sensors are of the passive infrared type (PIR); that the detectors further comprise at least one of the type for measuring temperatures, or for measuring water vapor concentration, or for measuring carbonic acid concentration; that the bottom comprises recesses in which food is arranged, the food being substantially in the form of a grain; that at least one mat is disposed on and as a second part of said first bottom, wherein the mat comprises food inclusions; that the mat comprises mat parts which are arranged as a pattern on said first bottom; that at least a single sensor is arranged in a part of such a hopper; and that said sensor is arranged in said mat.
    Moreover, the present invention relates to a eating mat with sensors as mentioned above.
    Further elaborations of the invention are described in the subclaims.
    In the following, with reference to a drawing, the invention is described in more detail on the basis of non-limiting exemplary embodiments.
    More specifically, FIGURE 1 shows a curve for the course of the number of chickens broken from the egg, FIGURE 2 shows a measurement of the humidity for a collection of hatching hatching eggs, FIGURE 3 schematically gives an exemplary embodiment of a method according to the invention, FIGURE 4 shows an exemplary embodiment of a so-called hopper tray, and FIGURE 5 shows a part of a rack in which some hopper trays are arranged one above the other.
    Where applicable, the same numbers for the same parts or parts are used in these FIGURES.
    FIGURE 1 shows a curve for the course of the number of chickens broken from the egg (relating to a collection of hatching eggs), with vertical numbers N, and horizontally the duration, standardized at three days, namely the hatching days, generally for chicken eggs from day 18 to day 21. The course of this curve is according to Gauss.
    Diagrammatically, a vertical line VL indicates where the so-called "moisture peak" can be expected for this type of egg. Because water vapor is released when a chick breaks out of the egg, the peak is an indication that the majority of the chicks have broken out of the egg at that time. It is generally known that about 80% of the chicks are broken out of the egg.
    In FIGURE 2, measurements of the humidity made in a hatchery space for a collection of hatching eggs as mentioned above are shown.
    Along the horizontal axis the time for the hatch period, between 18 and 21 days after starting in the incubator or incubator, is indicated, while vertically the vapor pressure of water vapor in this incubator, generally the relative humidity RH, is indicated in arbitrary units (arbitrary units, AU). It has been found that such a maximum, indicated by a vertical marking line, the percentage of hatched eggs is around 80%. The number of eggs that hatch afterwards decreases rapidly and also explains the decrease in the course of the water vapor pressure.
    The measurement of this peak in the vapor pressure is used as a reference point in the exemplary embodiment of a method according to the present invention and will be discussed in more detail below.
    FIGURE 3 schematically shows an exemplary embodiment of a method according to the invention.
    The method comprises at least the following steps: - monitoring the hatching of the eggs, whereby hatching signals are obtained for each such egg; - illuminating the chicks in said hatching boxes in a controlled manner on the basis of these hatching signals, and preferably also administering food to the chicks in said hatching boxes in a controlled manner based on these hatching signals; and - controlled transfer of the chickens to rearing compartments on the basis of these and further hatching signals.
    More specifically, as a function of time, with consecutive ascending tide dm oments t from t1 to t6 as indicated in the circle symbols bnks, the corresponding blocks 1-6 are given on the right-hand side, the blocks correspondingly consecutive to each other give the following hatch part periods in the method.
    Block 1 at tl stands for the start of the consecutive hatch subperiods, namely the start of the aforementioned 3 days, days 18, 19, and 20, in the case of hatching of chicken eggs. At that time, all hatching eggs are placed in the hatching trays mentioned, thereby forming a substantially sealed and separated collection of eggs in a hatching room in which the climate is controlled in a known manner.
    Block 2 at t2 represents the moment at which, for example, an infrared sensor measures the first movements of a chick breaking from the egg. This measuring moment is used according to an aspect of the invention; other ways of measuring are possible for measuring these movements or for determining this event. For example, but not exclusively, cameras, or also temperature sensors, can be considered.
    In general, and therefore to be regarded as a very general average, t2 is approximately 26 hours after tl.
    Block 3 on t3 indicates the moment at which the exposure is started.
    A suitable moment for this has been found to be a time up to 4 hours after t2, that is at the latest 30 hours after t1. More specifically, t3 = 28 hours is taken.
    Many solutions have already been devised for exposure, for example as mentioned in WO2007110861. It has been found that an adhesion cycle and light similar to conventional daylight gives the best results.
    Block 4 is a reference to the next reference point at t4, the so-called "humidity peak", namely a measurement of the highest water vapor pressure in this part of the breeding chamber where the majority of the chicks have broken out of the egg. As already indicated above, this measuring moment is used to stop the exposure at t5 according to block 5 soon after.
    This peak can be expected at a time of more than 2 days after the start of this hatch subperiod, namely at t4 = 50 hours after fluorescent.
    The subsequent time point t5 is determined after this peak in the whole of signals has clearly marked and is on average no later than 1 hour after t4.
    Finally, at t6 at block 6, the hatching process is stopped and all the chicks are transferred to appropriate breeding compartments. This time point t6 is on average 72 hours after tl.
    More in particular, according to the method of the present invention, an approach has been chosen for the treatment that largely approximates a conventional day cycle, for example consecutive light / dark periods of 8 hours of light - 8 hours of darkness, and so on. This means that for the subperiod from t2 to t5, approximately 22 hours, a division into 3 parts can be chosen. Depending on current conditions, or also on typical oak characteristics or variety characteristics, other light / dark indices can be used.
    A cycle with light-dark periods with a minimum duration of 2 hours can also be envisaged.
    FIGURE 4 shows a view of a part of an exemplary embodiment of a hopper 30. The view is about half in an isometric view.
    Such trays are generally known, made of a suitable plastic, easily washable, and with a size suitable for, for example, 80 eggs to cause the chickens to break out of their egg during the aforementioned approximately three days.
    As FIGURE 5 shows in a further isometric partial view (of walls and bottoms), these hatching trays 30 are layered in a rack 50, usually designed as a drivable frame or carriage, in an incubator or hatcher or hatching room, which is air-conditioned in a well-known manner is becoming. For example, 12 of these frames are located in such an incubation chamber.
    These trays 30 generally have at least a single bottom 31 and four wall parts, two of which are shown partially and the third as a whole, namely the wall parts 32-1, 32-2, 32-3.
    Furthermore, a mat 40 is shown, and in this exemplary embodiment centrally placed on the bottom 31. More particularly, bottom edges 31-1, 31-2, 31-3 are arranged to fit within these edges 31-1,2,3 to place mat 40.
    Depending on the design of such a mat 40, that part of the bottom may be slightly recessed. For example, such a mat 40 is designed as a layer of cardboard which can consist of two layers at the top and bottom with ribbed lines between them and further spaces which in the present case can be filled with food components. By choosing this upper and lower layer appropriately, for example and edible and sufficiently thin, this layer can be considered as food as a whole when pecking a chick. This food can for example be granular.
    In a further exemplary embodiment not shown, sensors of different types, for example for measuring temperatures, humidity, or CO2 content, can be arranged in wall parts of the outlet 30 or in parts of such a mat 40. Communication with this can for example be done with optical signals or radiographically.
    Furthermore, in FIGURE 5, a combination of sensor 60 light source 70 is used per exit tray 30. This combination or PIR device (Passive Infra Red) is described in NL2004377 and the relevant text is deemed to be inserted herein as a reference. Sensor 60 is, for example, of the passive infrared type for detecting movements, the operation of which is known to anyone skilled in the art.
    As indicated in FIGURE 5, these PIR devices 60, 70 are each mounted on a side wall part of a tray 30, for example clicked.
    It will be clear to the skilled person that the invention is not limited to the exemplary embodiments described. Further variants, for example those which come close to the exemplary embodiment shown, are considered to fall within the scope of the appended claims.
    For example, the detectors or sensors may be attached to the frame of a rack instead of the hatch trays, the cycle frequency may be that of daylight, but differences in intensity or small color changes may be applied, and nutritional supplements may be partly in mat parts and partly in specially applied parts. recesses are provided in plastic parts of the hatches. Furthermore, in the exemplary embodiment described, times, times, and periods are mentioned which are considered to be mentioned here only as an example. They are to be considered as an average for this type of eggs, and may deviate considerably from other breeds, and certainly from other types of poultry such as ducks, geese, or turkeys.
