Please help me. I noticed that my duck was limping so I made sure he was near food and water so he didn't have to move very much. Within days it is very swolen. Although if I touch if he doesn't help at all. I have him separated from the other duck and chickens so he can rest. I also wrap his leg with an ace bandage. I'm at a loss because nothing is changing. Please tell me if this looks broken or what it could possibly be and how I can help him!
