Okay I have never seen anything like this before and I'm going crazy trying to figure out what is happening to my ducks feet. I have a 6 month old male Muscovy Duck- last month I noticed he had a little limp to his walk. I took a look at it and noticed his webbings were both cut. I do lock them up at night but let them out during the day to free range in my yard. I have a small creek that runs from my spring house that they all go to and play in and hang around. So I figure okay maybe there was something sharp in there that may have cut it. It never got any worse and continued to check on it and then all of a sudden lastnight I took a look at his feet and I don't know how to put it but half of his feet were gone? His webbings and "toes" (except for his middle one) were just gone? His two toes were actually removed and stuck to his middle "toe" on his one foot. I attached a picture as well. If anyone can help me figure this out I would appreciate it!!!
