Please help... I found one of my EE pullets, 11 weeks, laying on the floor of the coop this morning. All of the others got up and went out when I opened the door, but she stayed there. She is alert looking around cooing...when she tries to walk her toes don't straighten out right and she sort of scoots on her knees. Does this sound like Mareks? They were the first chickens I hatched at home and they weren't vaccinated. If she has this will her siblings get it? Should I vaccinate them now? I read about the hypericum treatment, but I didn't want to try it until I knew for sure.
