I wentt out this AM to feed the chickens and my 9 MO Speckled Sussex hen stumbled down out the coop and promptly sat on the ground with her wings out a little. I picked her up to see if her legs/feet were injured....but they are fine. She then let out a gush of clear, watery diarrhea. The other chickens have started to peck her....I seperated her from them. Any help appreciated.
