You may be drawing the air out trough the needle but when you remove it the hole closes up and the problem is back so instead of a small hole cut the skin atleast 1/4 inch this hole will give the time you need for the airsack to repair
I had to start a new thread to post the pics (only way I know how).Wouldn't it depend on how bad it was? How blown up the bird is? If it is bad, it could have trouble breathing, and taking the air out would help. Can you post pictures?
