My female Mallard is limping on one leg today. She puts a little weight on it when walking. When standing, she holds her leg up. I'm thinking a horse stepped on it. I picked her up and felt her leg. Her nee (I don't really know what it's called) feels bigger than the other one. It must be broken shouldn't it? I put her in a pen with her buddy's. She looks like she feels good besides the broken leg. Also, I have her and two males. I know that's not good. I'm trying rehome one of the males. Did the two males do this to her? Thank you! I'll update on her progress. Right now I need some advice. Here she is. She holds her leg up This is a blurry picture, sorry. This is where it is swollen. This isn't her leg.
