i recently aquired several chickens from an older couple who are just getting out of the chicken business. after a couple of days i noticed that of the bantam hens i have one that has no toes and another that her toes are twisted sideways and seem to be scabbed over with a black looking scab or scale. what could this possibly be and what should i do? is it contagious to the other chickens? would it be best to just remove these from the flock altogether? would they still be okay to eat? other than trouble moving around they seem to eat and act fine otherwise. just getting started into chickens, so all this is new and am open to all suggestions.
