My goose was fine this morning, and ate a bunch of feed. but later I noticed a small bump on his chin. I figured there was something stuck there so I gave him some romaine to claw it all down. It got worse as time progressed, now it's like a small dewlap. It seemed very squishy like it's full of water. I'm pretty sure there's food lodged in there, because I pressed it, and there was only wheezing, (no head shaking and swallowing) because I closed off the airways. So im sure its swollen flesh. What should I do?
