I got new chicks recently and for the most part they are doing fine. However one day my cat slipped in and grabbed a Brahma chick, I managed to give him a smack and make him drop the chick. (Please note that I didn't hurt the cat.) At first she was limping, but her leg wasn't broken. Now she runs around with the other just fine, but a new problem occurred. How do I put this...? She seems to have partially filled up with gas or air. Her skin is more visible, though that could be molting but she seems too young. Her leg is miles better, too, but makes a concerning noise when I run my finger over it--like dry paper, almost. She's been like this for maybe 2, 3 days. She's only about 5 days old. Other than this she seems really healthy, as she eats and drinks and plays normally. If anyone could tell me why she's filling up with gas or air or what else could be going on, I'd greatly appreciate it.
