I have chickens that I let out every day to free range. I also have 14 Narragansett turkeys approximately 15 weeks old. They are in an enclosed run which is 32' x 20'. If I let them out to free range will they go back in at night like the chickens or is that not a good idea? I am not concerned with blackhead, I have several people around me who raise both and have never had a problem.
