My 2 month old gosling was found shoulder deep eating a moldy straw hay bale. That was 6 days ago. He stopped eating and drinking. I've been giving him electrolytes and save a chick from tractor supply. He's in the house in the bathtub. I've been trying to force the fluids and have his water in front of him. He's refusing to eat and drink on his own. He's losing weight. He's not moving in his own but his head is up and he's chattering. He's asleep on my lap wrapped in a towel. Any ideas? Will a b12 injection help? What else can I do?
