We have chickens and ducks right now. DH is talking about adding a few turkeys next year. From what I read you have to keep them away from the chickens. How far apart do they need to be? My chickens are fenced in totally so they can't get out. The ducks have a short fence that they do occasionally get out of. Any advice on raising turkeys? He is wanting the red or burbon ones, can't rememeber their official names.
