I have a chick that seems to rest an awful lot, I had not seen her eat or drink, so I separated her form the flock and gave her some food and probiotic water...then gave her a quiet place to rest... Upon observation it seems one of her legs is weak, but not easily detected so I'm not entirely sure if that is the case. She can stand on it, walk around, and even tries to jump on the rare occasion, but I'm guessing it may be sprained? She gets bumped about by the other chicks and generally retreats to a corner to rest. She is definitely not growing at the same rate as the other chicks, seems overall meak. Suggestions would be helpful...at this time I have her in a separate box inside the brooder with the other chicks (see photo) She has been resting all day and I noticed she didn't even get up to poop, because there are several poops right behind her sleeping bum.
