Many species-specific incubation requirements make the correct management of the incubator most critical. But mostly, turkeys have an incubation period of 28 days, with eggs needing to be turned over several times a day to help them grow.
For most turkey breeds, the incubation machine temperature should be 99.5 ° F (37.5 ° C) if the machine is a compressed air model, if the machine is a still air model the temperature should be set to 38.1 ° C (100.5 ° F).
