I have a backyard with a lake in it. So of course there's a lot of ducks there. One we hand feed and love. I do not know the breed she is. One day when i was going to feed her I noticed she as not using one of her legs. She will not let me get close to her at all. But I can clearly see teeth marks from one of the alligators in the lake. I am afraid to get to close because she only hops away and she might hurt herself more... She stays in one spot all day and doesn't move. No bones are poking out of the skin that I can see. I want to help her. Does anyone have any advise? Please help me.
