Hi, I have a 2 week old chick that has injured it's right leg and it appears swollen and red in the joint. I'm afraid she may have been dropped by one of my kids, but I'm not sure. The chick doesn't want to stand on the leg and is holding it up when standing. She's still eating and drinking and getting around, but not as well as when we first got her. I'm new to chicken keeping, so I'm not exactly sure what this is and what to do for her. Help!
