Can you tell if that is the crop, where food is stored until it moves on through the digestive tract? The crop is on the chick's upper right chest below the neck. They are usually prominent and easy to see in chicks as they fill up with food and water. If injured, air sacs can leak forming a soft balloon-like bulge. Here is a link about that:
