I have a chick who is clearly the smallest out of 16. The other chicks are getting big and she looks to have stayed the same. She seems to be having some problems walking. When she really wants to she can walk/run holding her wings out to steady her. Most of the time she just lays down. I feel very bad for her because she sometimes gets run over by the other chicks. I put her in a box by her self but she just crys until I put her back with her brothers and sisters. She seems to be eating and drinking fine. Her vent is clear also. I did notice that her left foot doesnt look quite right. Kind of looks like maybe something is wrong with it. Im not really sure. Like I said she can walk and run when she wants to but just doesnt do it often. What do you think I should do? Also these are day old chicks purchased on wed 5-12-10.
