I did.
I kept poults and had plans to separate them but we ended up getting rid of everything.But However the poults made it to about four months.
I noticed pecking order issues.The turkeys and chickens squabbled a lot ,unsure of how the situation would turn out had we had them until their older, now their with the chickens on some other farm, so not sure how things transpired.
However I have kept ducks since I have been raising chickens and they usually do well.With good space and things to to keep them interested in,they usually avoid conflicting.However I do notice when hormones spark in the spring there's some tussling between the drakes and roosters.
