It could maybe be the crop? Since they don't have teeth they store food in a crop to be digested for them. Does it feel like there's food inside? When I got my chicks I got worried cause I also noticed big bulges in their necks and I would touch it and it felt like hamster cheeks when they store food then I found out that yes they store food because they can't chew
Hopefully that helps I'm not 100 % sure tho just a guess
