Hi! We're new to chicken raising and currently have 8 chickens that are about 8 weeks old. We have 2 Americanas, 2 Asian Blues, 2 Rhoad Island Reds & 2 Dixie Rainbows. We noticed feather loss about 3 weeks ago while they were still in the brooder box inside our house. I thought that maybe it was because they didn't have enough room and we've since moved them out to their coop where they have lots of room and they free range every day. But I'm still seeing feathers every morning inside the coop and in the yard. I've checked a few of them but don't see any parasites on them and haven't noticed any little bullies among the group. I'm at a loss on what to do, please help.
