Pale comb on rooster

[satkins]

He is very listless. Not eating much, does not crow, his tail feathers are drooping. We have had to put 3 hens down because of Mareks. Do you think this is the first sign of it's return. I do not want him to suffer. His comb in very pale and droopy.

It's a possibility that it could be Mareks, especially if you have a history of it in your flock. I'm going to post a link to a thread I started about my little roo and let you read that. It's long. Starts out with symptoms similar to yours and has my necropsy report included which revealed he indeed had Mareks. Check it out if you have a few minutes. I included pictures as well.
