I have a 4 month old silke chicken that about 2 months ago was unable to get into the coop with the rest of the chickens. I took inside and noticed that her leg looked funny and separated her. Slowly she went from being able to walk to not at all, and when she stood up she would fall over and do a split, I treated with vitamins (E and B complex) I thought that she may of had mareks but she has survived this long and none of the other chickens have had it. Just recently she was able to stand again and walk a little i dont know whats wrong and what I should do. I hoping that because she is able to stand that maybe she will get stronger.
