Hello, We recently inherited 13 chickens with the purchase of our house. One appears to be lame and doesn't move or do much if she does move its extremely slow. Now another chicken appears to have something wrong with it. It is falling over (on it's face) It can't seem to stand at all and it's 3rd eyelid on it's left side is always closed. The eye opens occasionally and looks fine when it opens. From what I have read it's either vitamin deficiency or Mareks? Any ideas as to what I can do to help these chickens? I also brought 6 of my own chickens in the move and am now concerned for all of them. Ugh any help would be greatly appreciated.
