For the past couple weeks my chicken, Red, has been limping. At first I thought she had leg mites (we had a case of it a few months ago but seemed to have successfully treated it). Her feet had begun turning white and her scales were strange. I had a friend who knows more than me about chickens come by and my friend thought she saw a cut on the bottom of the chicken's foot. I have been unable to find the cut, but I've restarted the mite treatment and also sprayed her with blue-kote. The whiteness on her feet has disappeared and her scales have not worsened. I should also mention our other chicken, with whom Red is in close contact, is showing so symptoms of anything at all. In the intervening time she's been using less and less of her leg, until today it seems like she has no use of the muscles all the way up to her hip. She just limps along on the knee and when I touch an ice cube to her foot, I get no reaction. When I try to manipulate the foot and leg, there is no muscular reaction, though there still seems to be some muscle tone. Red doesn't seem to be eating much and hasn't laid in three days. Has anyone encountered this before? Is my chicken doomed?
