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.
