I have a 3 week old EE chick with swelling on it's left side. The whole left side looks blown up like a balloon and is pushing the wing out a bit. When I put pressure on the swelling, it gave like a balloon, so I'm pretty sure it's filled with air, and not fluid. When the chick breathes out, it makes a raspy sound. Any ideas on what this could be? I was thinking of taking a syringe with a needle, and trying to suck some of the air out, but if the air is coming from it's lungs, I wouldn't want to hurt it or potentially make the problem worse.
