About two weeks ago we found one of our hens dead in the coop with no obvious injury and no prior warning of illness. Now I have a hen (same breed) who is found twice now on her back and she seems like she is stuck there. When we turn her right side up she seems a little wobbly at first then seems ok for the remainder of the day. Does anyone have any experience with this? I tried to search for why this would happen but could not find anything and I am REALLY worried about her. Could the two be related? The hen is about 4 1/2 months old and is a Cochin. Otherwise eating/drinking fine.
