Abstract: An improved system for the incubation of exotic bird eggs contains a flexible bladder as an essential component. The system includes an incubation unit, system heat exchange liquid, a heating unit to warm the heat exchange liquid, a pump unit, and conduits to circulate warmed heat exchange liquid in the system. The incubation unit includes a housing, a bed of soft wood chips or equivalent bedding material contained within the housing upon which an array of the bird eggs is supported. The flexible bladder has a relatively flat bottom portion that is supported by and covers the array of bird eggs. Inlet and outlet tubes extend from the bladder and are associated with the conduits whereby warmed system heat exchange liquid may be circulated from the heating unit through the bladder interior to supply heat through the flat bottom portion to the bird eggs to warm and incubate them. A related method of bird egg incubation based on the bladder is also disclosed.

Abstract: An avian feeding device has a bird cage of the wire mesh type and a feeding tray that includes a bifurcated backing member with a mounting space provided between a front sheet portion and a rear web portion. The cage has a rectangular opening formed in a wire mesh, vertical wall by cutting away an adjacent plurality of its vertical wires. The tray mounts to the cage through such opening with downward movement to bring a horizontal wire of such mesh, vertical wall into the mounting space. No handles or like protrusions are needed to assist in removing the tray for service since it may be removed from the cage simply by applying upward pressure to the lower section of the rear web portion of the backing member and withdrawing the tray through the rear mesh wall opening which is of sufficiently small size that birds contained in the cage can not escape even with the feeding tray removed from the cage.
