Hi All - I have a flock of 7 chickens already for eggs (so many eggs), and we're thinking about raising turkeys for meat. I know that turkeys and chickens need to be kept apart and that I'd have to be careful to make sure I didn't track one set of germs into the other coop. My question is: how far apart do they need to be? I have an acre, so I can put them about 150' apart if it was that serious. But I'm wondering if 30 or 40 feet would be adequate. Thanks!
