My 8 week old chick has a hurt leg. While I was trying to gather her and the others up this morning, I accidentally stepped on her. Needless to say, I feel terrible about this. She seemed to be walking around normally at first. But, later on she was limping. I checked for breaks, swelling or dislocation. She didn't have any of these. I put ice on her leg and she's in a large crate with the other chicks. She's laying down with them eating and grooming herself. Is there anything I should be looking for? Is icing and rest enough?
