Hi, my female duck took off for the day and returned home that night. I found her the following morning and she can not walk on her leg. She puts very little pressure and uses her wing. The webbing between the toes has been ripped. It seems as though maybe a snapping turtle grabbed her leg while swimming. The joint directly about the foot is very swollen and very warm. I'm not sure if the joint is broken or everything is very sore. I have her in a tiny cage with fresh blanketing, food, and fresh water. She is eating, drinking, and pooping. I soaked the wound with warm water and applied blue coat to stop infection. I am receiving an antibiotic from tractor supply as well. Any advice or knowledge would be greatly appreciated!!! I don't want to put her down.
