I have a duck that has been limping for a couple days, I took her in and isolated her from the rest of the flock.. she was a able to stand on one leg but today she was only laying down. Nothing is visibly wrong that I can tell.. could a rooster do this from trying to mount her? Anything I should do? I have her in the tub right not with water so she can get a break from standing on her legs. She is eating and drinking fine, I can post videos if needed but I can really get any good pictures as It’s a little difficult to get a good one.
