I am not sure what is going on with my 1 1/2 yr old hen. I noticed something was wrong when the other girls kept picking on her. Then her wings started looking droopy. I separated her for a few minutes to feed her hoping that if she ate good she would get some strength to fight back. Yesterday I separated her completely from the group and brought her inside to a cozy place with a heat light. She ate and ate and ate then drank and drank and drank. Now she has very loose poop. Her wings seem not as droopy but she hadn't laid an egg either. However she may have not been laying all that well before. I have 10 girls so it is hard to tell who is actually laying. I noticed all this starting Friday night. It is now Tuesday. Any ideas of what is going on?
