Hi I have 13 chickens and My 4 year old Rhode Island Red is walking wobbly and taking High steps, i seperated her from my other chikens. I'm not sure if it's Mareks. I had to put my Dark Cornish to sleep back in 09' for Mareks. Any Advice? Is their any Cure? Should I take her to a vet? Should I have her Euthanized?
