This poor chick was found with its head stuck in a fence and cut all its skin off around the neck. I've cleaned up the wound to where I'm not too worried about it anymore but there is a bubble that looks like it's filled with air by its neck. Every time it eats, the bubble gets big and I'm thinking that as it's eating and filling up itscrop, it's pushing the air in that sac. What can I do for this poor baby?
