Hi, my chicken was walking a bit strange for a while and it gradually got worse and now she is using her wings to steady herself and holding up one foot. She has some bad scaley leg mite that we are trying to treat. We have been giving her salt water baths as she had a cut on her foot which seems to be gone now but I've noticed some dark purple spots on her leg and foot (bruises?). She is still eats and drinks and is very alert. Any help would be much appreciated, she is a lovely hen.
