I bought 2 goslings and one was a little small, the runt possibly. He seems fine eating and drinking, but his neck is not straight like the other goose it's like he can't hold it up. I assumed it was wry neck, and have been giving poly vi sol, vitamin e and selenium for a week. It's not helping. He's still eating and drinking water with sav a chick electrolytes. I tried to put a splint on him and he flipped out. Could it be something else?
