So sorry that he is no better. Have you gotten any results from the necropsy from the state vet? You might try to call them, which might help to know what to do about Motley. Vets are so expensive, and sometimes they don’t always have a lot of knowledge about chickens. I can’t remember if I have mentioned the vetdna website where you can send blood serum in to them for a $20 Mareks test. Your vet might be helpful with drawing blood, but you may be able to do it yourself at home for less money. Here is the website to contact them in TX for the details:
