This a chicken about 6 months, It was bitten by a small dog in its side. There is no puncture wound but alot of swelling. One wing looks broken not moving the wing. It will stand but wont walk. What do i do for it? I thought it would die but it has been a couple of hours? Since i dont know if it is bleeding inside i have given it anything. It is sleeping when you leave alone but will move its head and look at you when you walk up to him. what is the best way to treat this???thanks in advance.
