My duck got attack really bad by a dog ,Right were the wing connects to the body. He was bearly hanging to life. he was a little stronger but wont eat or drink and is losing his strength. Im already worried that his injurys might kill him now he might starve himself. I have already made him a mix of water and feed, he hasn't even tried to drink it or anything. I have him inside in a warm cage with comforting bedding. Im not sure what to do from here.
