While I was on vacation, it seems that our 6 week old Speckled Sussex might have developed a vitamin B deficiency. She stopped moving around and just wanted to sit. Wasn't really eating or drinking. She was moved to a box to recover away from the others. One of her feet has curled toes. We are giving her some Poly-Vi-Sol daily since last Thursday. She eats and drinks. Just lays there still, though. Doesn't seem to be getting better much. What next? Is there still hope for recovery where she'll walk again and the likes? Thanks.
