I have a 10 week old yellow turning white duck. He was fine in the morning when I fed him then i went out a few hours later due to the others making a ton of noise. I found my little man on his back. The only thing I can think of is him jumping off of things he's always doing it. He jumps from the laying box's and tries to fly. He can't fly. But I'm not sure what to do. He's eating and drinking. (I'm not sure if its a male,I just call it him) I give them all the vitamins in the books inside the water every other day. Also he eats flies outside and the scratch i give him. There's 3 other ducks and 11 chicken's in with him. Anything anyone can think of of appreciate!
