We have one hen that is smaller than the rest. Up until the point she started molting they all got along just fine. Unfortunately when she molted and looked different they started pecking her. I ended up having to separate her in order to heal her up because she was bleeding and it was only getting worse. Now after having reintroduced her into the flock, she is still at the bottom of the pecking order. They are not allowing her inside the coop, to eat or drink, or roost. We have to go out there and stand there while she eats and once she is roosting, we shut off the lights and they allow her to stay inside. If we don't she is stuck outside in the cold. How do I change this behavior? We normally keep water outside in the run but it's winter and will just freeze solid. She needs to be allowed into the coop to stay warm and eat and drink. Ideas?
