I had 7 chickens and when I came home from a morning away, 3 of them had gotten out (possibly hiding in the bushes) and one was lying underneath the coop, barely moving. I'm kind of assuming something got to the other ones, but it's possible that they had just been out long enough to wander away as they followed bugs. There are a lot of feathers in the run but no bodies or blood that I can see. My main concern is the one that was barely moving. She looks like she may have been attacked and just be lethargic/injured but I don't have any experience with sick chickens so I'm not entirely sure. I did have one broody hen but I'm not sure if this is her or not. Any advice?
