Anyone with experience placing incubator hatched chicks under a desperate broody? tips? advice? suggestions? bad idea?
A few questions to consider
1.) Is she a first time Broody?
2.) Was/is she currently sitting on eggs or does she have any chicks.
Also depending on the feedback you get here might be a good idea to post or do some reading on the broody thread.
