My baby mallard is 2 weeks old and and we think someone grabbed him weird cause once he was put back in his cage his foot was crumpled and was putting no weight on it. It had been 2 days. His leg seem swollen. When you put him in water he does not try and swim with it. Will it ever heal? Will it heal wrong ? Do I splint it? Should I separate them? There is only two baby's. Please help thanks!
