This evening my female mallard duck was quacking and I thought that was really unusual for her. I went down to check on them and one of my male mallard ducks had gotten its foot stuck in the cage wire. I hurried and got it out but now he is limping/hopping and favoring his foot. He was "licking" it, too. He can walk on it when he absolutely needs to, though, so it's not broken. Please help. What should I do??? I'm so so worried. Could it be sprained or bruised??? Help!!!!
