I have a young light brahma cockerel who yesterday started being a bit "wobbly" on his legs. I'm hoping this isn't Marek's. He is the only one out of 16 youngsters affected. He is eating very well and poop looks normal. It's just as if his legs aren't working properly. When he turns he loses his balance. He is using both legs but very unsteady and when he walks it looks like his legs are turned in at the knees and he seems to move them in a very exaggerated way. It's hard to describe, but it looks like someone walking on stilts. He is about 6 weeks old and this has just started. I'm grasping at straws. I thought maybe vitamin E would help but don't know how to administer it or even how much to give. Please help!
