I have a hen that is not feeling very well, i found her last thursday laying on the ground and not able to keep her balance. so i brought her into the house and warmed her up and it looked like she was doing better on sunday so i put her back in with the other chickens. She did good for the two days and this morning she was unable to jump up on the roost they have in the yard and i also noiced that her comb is very limp. I hope some one can help me out with her plus all the hen are molting to. please help
