I have a 4 year old buff Orpington rooster that showed up as a stray 3 years ago. So I'm thinking he is 4 now. He has Always been a healthy chicken, but accident prone to leg injuries. But I'm worried im dealing with Marek's now. Today he can't walk, I did see him stand up once. He also made it into the coop tonight. He is my pet and I'm devastated. I've called specialist at a university and she said it's not common for an adult that age to get Marek's but it's not to be ruled out. How can I care for him, make him comfortable and feed and watered and when to know when I should have him put down? I looked him over last night looked great but he did flinch over one section of his leg I touched. But when I watch videos of Marek's he looks just like those chickens. I'm just so confused. Thanks....
