So one of my baby ducks is walking really weird. His leg isn't deformed or anything, he just doesn't put pressure on it. He can move it, he just scratched his head with it as I'm writing this post. He's eating, drinking, and pooping a lot. He is way smaller than the others. But in his defense, he was the always smaller than everyone else. He can walk, well more like hop and he'll put his hurt leg down to balance himself every now and then so he can move it. And he uses it to swim. Is it just a sprain or something? He's been doing this for a couple days now.
