Agree with sourland, that's definitely true. Avoiding cross species imprinting is very important for things like that.
I reared turkey chicks under hens for a few generations before cross species imprinting really took, and then without warning I had a tom turkey that had never shown interest...
Never heard a chook called a biddy before, but hopefully people get the gist of it, lol.
I agree, except of course there is always the exception to the rule, those flocks where the drakes don't stray from the ducks.
Always a risk keeping mixed species, but so many aspects of keeping animals...
