I have a 7 month old sizzle rooster. Here's the story I found him layibg in the coop on day unable to walk. I took him into the garage into his own cage. I left him in there couple day goes by and now hes able to walk again pretty good. He eats and drinks. But his head bobs in a circle. My friend said they seen him trying to fight the other chickens a few days prior. So I dont know if one of the largefowl rooster got him. Or maybe he got mareks somehow. No new birds have been acquired for about two months. Maybe longer. Anyway to test for mareks? What do you thibk it is?
