I had noticed about a week ago that my other girls were picking on one barred rock, she eventually just stayed in the coop. She was not eating much and had become very weak. I seperated her, and she still is not eating. She is laying down and not standing much, tho she did step out of her little pen once today, I had to pick her up and put her back in, she seems to weak to move. I noticed her poop was white and runny, Could it be that she is egg bound? How can you tell? She is almost a year old, This is the first time I have had any problems with any of my girls, and I don't know what to do.
