Yes, I have read that too, I just thought it was normally more rapid than what you are experiencing - but I have no idea really.This is what I have on Marek's
What I don't understand is how he could have gotten it if every chick was either vaccinated or hatched here? I haven't introduced adult /older chickens to my flock, only vaccinated chicks. So, where did it come from?
I don't think it will help you decide what to do with your poor roo, but there is a PCR test for Marek's. It might help you with future flock management to know if you really have Marek's in the flock or not.
You can get it done at a private lab in Texas (if you are interested I can find the link) and for all I know the State vet would do it too.


He is only a year old, and near as I can tell, he has Mareck's.
All my chicks have been vaccinated and/or hatched on site....no birds brought in but vaccinated chicks, so I am not sure how he got it, but it seems to be the classic symptoms and I can find no other reason. He can't use his legs. I have been working with him trying to supplement vit. B and exercising legs 2 x per day...and it has gotten worse, not better. Poor guy, he is sweet and was a good boy to the girls..... this is so hard, but, watching him quietly yesterday...I realized that I was so attached that I ignoring the obvious. He initially (quite suddenly - after a fight with another roo) was very weak in the legs and I brought him inside to protect him and work with him (initially thinking it was pain from injuries.) Despite my efforts, legs are worse...now he has no control of lower legs at all, no reflex nor grip motion with feet, nothing.
horse pee and poop. What's wrong with your brandy
