Went out to check on the girls and found one of my ISA Browns sleeping, standing up, on the ground. She is also not one to be held but isn't even fighting to get away when I pick her up. When she opened her eyes there was a red ring around the outside of her golden yellow iris that looks like its working it way in towards the pupal. Shes just over 20 weeks, has not started laying and there is the possibility of Marek's in our flock but with Marek's it says the eyes turn grey so any ideas? I'll try to get a better picture later when I have some help holding her.
