DETAILED DESCRIPTION OF EMBODIMENTS

[0044] FIG. 1 shows in perspective view a climate chamber 1 for hatching chicks 3 according to the method of the invention. The climate chamber 1 is configured to control the temperature and humidity in the climate chamber such that newly hatched chicks can be fed in the climate chamber 1. The climate chamber 1 comprises a ventilation means 5 to generate an air flow A, Ar through the climate chamber 1.

[0045] The climate chamber 1 has a bottom wall, a top wall (not shown), a front and rear side wall and a first and a second end wall that enclose the interior of the climate chamber 1 to allow a recirculating air flow. The climate chamber 1 comprises a number of heat exchangers 3 for heating or cooling the climate chamber 1. The temperature of the climate chamber is controlled through heat exchange between the air flow and the heat exchangers 3. The heat exchangers 3 are air-permeable to allow the air flow to pass the heat exchangers 3.

[0046] Here, the climate chamber 1 is subdivided into climate chamber compartments 4. The air flow A flows from the ventilations means 5 through all climate chamber compartments 4 and returns through a corridor or passageway back to the ventilation means 4. Such a climate chamber compartment 4 is configured to match the dimensions of a stack 13 of crates 2. Such a stack 13 is normally handled with a trolley (not shown).

[0047] FIG. 2 shows a cross sectional side view of a crate 2 for use in the climate chamber 1 of FIG. 1. The crate 2 is configured for accommodating a group of young chicken 3, like a group consisting of 40 to 100 young chicken. The crate 2 is stackable. Therefore, the bottom face 11 can be placed on top of another crate 2. The chick 3 rests on a floor element 10. The crate 2 comprises a trough 6. Here, the crate 2 has two troughs 6. The two troughs are arranged at opposite sides of the crate 2. The trough 6 contains live feed 7 in order to supply the newly hatched chicks 4 with live feed 7 in the crate 2. The live feed may comprises insects and/or worms, in particular one or more of the group earthworms, larvae, silkworms, mealworms and combinations thereof.

[0048] FIGS. 3a and 3b show each an embodiment of a trough 6 of the crate 2 according to fig. The trough 6 of FIG. 3b is subdivided by a partition element 8. The partition element 8 divides the trough 6 such that there is an intake opening 39 for filling the trough and an outlet opening, different from the intake opening, from which outlet opening the chicks can take their food.

[0049] FIG. 4 shows a stack 13 of crates 2 for use in the climate chamber of FIG. 1. In particular the stack 13 is placed in a climate chamber compartment 4. Here, the stack 13 adjoins a heat exchanger 3. In this case, the troughs 6 are arranged with the heat exchanger 3 and the troughs 6 are accessible by the chicks 3 from the interior of the crate 2.

[0050] The crates 2 shown in the FIGS. 2-4 are used in the following way in the method of feeding hatched chicks 3 in a climate chamber 1 during a first stage of life from hatching. Hatched chicks 3 are placed in the interior of the crate 2. These newly hatched chicks are transferred to the climate chamber 1 by placing the crate 2, in particular a stach 13 of crates into the climate chamber 1. These newly hatched chicks are transferred to the climate chamber 1 within the first 1 to 4 days of life, in particular as soon as possible after hatching. The chicks 3 are supplied with live feed 7 in the climate chamber 1. Therefore, the live feed 7 is placed in troughs 6. The live feed 7 contains e.g. mealworms. These troughs can be part of the crate 2, see FIG. 2-3, and/or part of the climate chamber 1, see FIG. 4.

[0051] As an option the climate chamber is transportable. FIG. 5 shows a side view of a transportable climate chamber designed as a trailer 14. The trailer 14 comprises ventilation means 15 to drive an air flow 16 that runs through compartments and heat exchangers 17. The compartments and heat exchangers 17 are schematically shown.

[0052] In use, the trailer 14 travels while the interior of the trailer is filled with stacks of crates 2. It is conceivable that both type of crates 2 as shown in FIG. 2-4 and FIG. 6 can be transported with the trailer 14.

[0053] FIG. 6 shows a stack of another embodiment of crates 2. An egg tray 18 is shown in assembly with a crate 2. Here, a stack of two assemblies of a crate 2 and an egg tray 18 is depicted. The crate 2 provides a chicken accommodation space 22 for hatching and rearing chicken. The crate 2 comprises troughs 6 at opposite sides of the crate 2. The, here separate, egg tray 18 is arranged on top of the crate 2. The crate 2 has an open top such that a chicken may enter the chicken accommodation space 22 through a passage 21. The tray 18 contains a number of eggs 19. The tray 18 comprises a number of egg accommodation spaces 20. In this space 20 the eggs 19 are firmly held such that the eggs 19 may be hatched in a controlled manner. The tray 1 has a number of passages 21 for a chicken through which passage 21 a chicken hatched from an egg 19 may pass through the tray 18 and enter the chicken accommodation space 22 located below the tray 18.

[0054] The crates 2 shown in FIG. 6 differ in use with the crates 2 of FIGS. 2-4 in that the chicks hatch directly above the crate 2 and make their own way into the interior 22 of the crate 2. Therefor, the step of transfer of newly hatched chicks from outside to the inside of the climate chamber 1 is not required. Instead, eggs are transferred into the inside of the climate chamber 1.

[0055] In FIG. 7-10 different embodiments of a troughs for use in a crate of FIG. 2 or 6 are shown. All the troughs 6 have a bottom 12 to support the live feed 7, and an inner 27 and outer 28 side wall. Here, the trough 6 is subdivided by wall elements 26. All the troughs 6 comprise means for maintaining the live feed 7 contained in the trough 6. The troughs 6 differ in the type of means for maintaining the live feed 7 contained in the trough 6, as will be explained.

[0056] FIG. 7 shows a grating 23 to maintain the live feed 7 in the trough 6. The grating 23 has openings 24 and ribs 25 between the openings 24. As an example a wall elements 26 has a trough interior surface 41 having a surface structure to impede climbing of live feed out of the trough. The surface structure is schematically depicted and can be obtained for example when manufacturing the interior surface, or by tooling or coating the interior surface.

[0057] FIG. 8 shows opposite trough walls 27, 28 each provided with a respective sloped section 29, 30 to maintain the live feed 7 in the trough 6. These sloped sections 29, 30 narrow the outlet opening 40.

[0058] FIG. 9 shows opposite trough walls 27, 28 each provided with a respective sloped section 32, 34 to maintain the live feed 7 in the trough 6. These sloped sections 32, 34 are arranged with a respective projection 31, 33.

[0059] FIG. 10 shows opposite trough walls 27, 28 each provided with a respective concave section (36, 37) as seen from an interior of the trough 6 to maintain the live feed 7 in the trough 6. These concave section 36, 37 are arranged with a respective projection 31, 33.

[0060] FIG. 3A schematically shows as a dashed line an edible enclosure 38 that surrounds the live feed 7 to maintain the live feed 7 in the trough 6.

[0061] It will also be obvious after the above description and drawings are included to illustrate some embodiments of the invention, and not to limit the scope of protection. Starting from this disclosure, many more embodiments will be evident to a skilled person which are within the scope of protection and the essence of this invention and which are obvious combinations of prior art techniques and the disclosure of this patent.
