I have a four month-old cochin who just stopped walking on Friday. Found her under the coop, she couldn't come out. I pulled her out with a rake and isolated her for the night. Since then I've discovered that she can't walk or stand. Her legs don't seem to work. So now I have a lovely slacker who sits in a wooden soda case tray watching and chattering all day. She eats, poops, doesn't seem to drink, and has deep conversations with the cat. What's going on here?
