I have recently moved my daughters ducks and chickens to my house. One of her ducks was injured by her three siblings. She worked with her and had her back to normal and just prior to me getting them they hurt her again. I’ve been doing all the things that worked before. She is isolated from the others but can still see them. She has her own pool plus I use a large pool to have her do extra swimming to strengthen her legs and try to have her follow me around the yard. I had noticed she didn’t want to stay in the water and she looked like she was shivering and today when I picked her up I felt her legs and the one she’s barely using is warm. I work in the human medical field so that tells me she has an infection but where and what kind? What is causing the lameness and what can I do to help her? Thank you.
