I have a chick that is about 2 months old. A week ago I was in the coupe feeding the chickens and I went to move and he ran under my foot just as I stepped down. It was unintentional, and I feel really bad about it. I thought he was going to be fine until yesterday. I was looking at him and noticed that he was more corpulent than usual. I picked him up and he had a big air bubble under his skin, on top of his thigh and rib cage. It seemed to cause him some discomfort so I pierced it and let out the air. The air did not have a foul smell and I was able to get it all out. However later that day he was swelled up again so I repeated the procedure. Then today he was once again inflated, however it appears as though some of the lower intestines are moving under the skin where the bubble is. I am not sure if this is due to displacement by the air or for some other reason. He is eating fine and running around as usual, but this situation is bothering me. I thought about just dispatching him, however he is the first and only chick that we had hatch so he has a little more emotion attached to him. I am not sure what to do, should I just let things go and see what happens, put him down, or attempt to preform surgery and try to put the intestines back in place. Sorry for being so loquacious, I just wanted to make sure I gave an accurate picture of the situation at hand.
