I have 6, 10 month old Peking ducks. They are in an uncovered large pen inside our fenced in the yard. The tree canopy has protected them all summer. We never had a problem until last night. A hawk attacked one, the largest one and tried to lift him over the 4' fence of their pen. We caught him in the act and scared him off! We brought Truffles inside to take care of his wounds but I am not sure if he is going to survive them. What can I use on them? Please help? He did get into the water tray, I placed in the crate because it was bloody. I'm not sure if I should try to feed him. His eyes are shut and he has a wound on the side of his jaw line.
