Serma hen perfectly healthy with young chicks. Found her at opening of co-op with beak stuck and on her back. When I seen her I thought her neck was broken she was so twisted. I helped her out and she was very dazed. Left her with her babies but she kept falling over on her side. I put her and babies in isolation. Seems to be getting worse. Falls back on butt and is always laying on side. I don't see anything obviously broken. When outside she would be more active. Should I keep her in and support her somehow. Or let her run and see if gets better. She was out for 2 days and now in house for 2 days
