So if you are keeping them locked in a barn, are they getting lots of sun in there, I am picturing a dark barn and I doubt a peahen is going to want to lay in a dark barn. Why not let them free range? If they like the barn I bet they would come back in and lay in it. I've seen them do that. I think they know that laying in the woods is dangerous. Even feral populations around here will lay up next to houses and even on rooftops lol. The birds aren't tame but I think they know that bobcats and other big scary predators would rather not come that close to civilization if possible. Just a thought!
