Hi, my BO chick is two weeks old. She was fine as of yesterday walking eating and drinking. Then when I looked at the chicks before bed, she was laying with her wings out, I thought maybe she was just really tired. This morning she was still doing the same thing, I picked her up and then noticed she wasn't using one of her legs and was using her wing out to compensate. I pulled her out of the brooder and feed her by hand and gave her some water. When I put her back in, some of the other chicks pecked at her so I divided them. I read this is maybe a vitamin deficiency? I have baby vitamins, but they have Iron in them and what I read said no Iron, does anyone know why? Will it hurt to give it to her, is it toxic? Any other advice? She is much smaller than the rest of the chicks, Im just not sure she will make it.
