A low profile brooder is provided, comprising a venturi, a burner base, a burner cap, and a baffle. The burner base and the burner cap reside adjacent to each other, with the burner cap disposed above the burner base and with a distribution chamber between them. A central axis is defined. A venturi resides below the burner base and is in fluid communication with the distribution chamber at the central axis. The venturi defines a fuel flow path between its upstream and downstream ends. The fuel flow path resides at least partially at one or more of an acute angle, a perpendicular angle, and an obtuse angle to the central axis. A baffle resides in the distribution chamber between the central axis and the periphery.

A method is provided, wherein the eggs which are pre-incubated in setter trays are transferred to the poultry house in these setter trays. In the poultry house, a layer of insulating covering material is provided on the floor of the poultry house, in one or more strips. The covering material comprises, in particular, litter which is applied in a layer thickness of at least 2 cm. By a set of egg pickup members of a transfer machine, the pre-incubated eggs are removed in the poultry house from the setter trays, after which they are positioned on the covering material by the transfer machine. In this way, the eggs can be placed in the poultry house efficiently, with a minimal risk of damage to the eggs a high hatching rate being ensured.

The invention relates to eye-friendly green-blue mixed LED lighting methods and systems for chicken houses. In a chicken house, an evenly-distributed cyan light environment may be created for rearing broiler chickens. The chicken house may include mixed LED lamps associated with the cyan light environment, and the mixed LED lamp may be formed by combining green LED beads and blue LED beads on a lighting fixture with a mixing proportion of from about 0.2 to about 5. The mixed LED lamps may be used for about 24-hour lighting in the first three days of the breeding period. From the fourth day of the breeding period, the daily lighting duration may be progressively decreased by about one hour every day. The mixed LED lamps may be evenly arranged in the chicken house to form a square array.

The present invention relates to a hatcher basket for holding newly hatched birds in an incubator. The basket has: - a pair of side walls on horizontally opposite sides having a plurality of horizontally-extending openings through them; - a horizontally-extending trough which is attached to the exterior of each side wall and which can contain feed for the newly hatched birds; - the bottom of each opening in each side wall being located at the same distance above the bottom of the side wall; - the top of each trough being located at this same distance above the bottom of its side wall; and - the size of each opening being significantly larger than the head of the newly hatched birds but significantly smaller than the thorax of the newly hatched birds.
