Hi everyone. Last week I had a sick hen and ended up having to euthanize her and took her to the state university for a necropsy. I got a call today that she had marek’s disease. She was about 1 1/2 years old. I am really worried for my other girls and roosters. We did a full coop clean out on Sunday. Can the others get mareks? She had been isolated for over a week before she died. How do I know if they have it? What do I do? Any info/help would be so appreciated. I cannot bear to go through this again.
