I have a chick here that is about 5 weeks old who got into the back yard and "played with" by one of our dogs. Not sure how long she was out there but our oldest border collie was protecting her from the rest of our dogs. She doesn't have any visible wounds, she is trying to chirp and she has flapped her wings a couple of times. I am worried she might have a collapsed lung though. I turned her over and whenever she inhales only one side fills up with air and I hear a faint popping noise. Any ideas here? Oh, and she is drinking water.
