All my peas are confined and the chickens are free ranging (and some in coops). I haven't had a problem with blackhead yet and we did free range some turkeys a while ago. They ran with the chickens and could certainly have been affected, but we never had a problem with that. Two were run down by a pickup and the rest wandered off with their wild brethren. Hence, all future turkeys are not free ranging, and I'm very cautious about free ranging a peacock,
I'll see about some pics this weekend. They came from my uncle's farm where he lets them all free range. He has some pieds, black shoulders and white (and maybe some others), so the genetic makeup of these is a mystery. If I can get some good pics, maybe you all can tell me what I have, though the anticipation of not knowing has it's charm too.
