i am sick of foxes and spend hundreds of pounds trying to protect my chickens. yesterday i found one looking very sorry for itself and not able to balance. i have discovered to my horror she has lost a leg. i can't see how. the coop is attached to a run and is stillfirmly attached. there is a small gap between the two but hard to inagine a fox fitting it's nose through.
have fed bathed and watered the chicken but i expect she will not recover. the fox comes daily to the coop to have a look. i have never noticed any other preditor and cant see how the fox achieved this.
