Missing feathers on neck under beak

[Cellomama2]

I will be trying some of these other suggestions but why would the other chickens be mainly pulling feathers from under the neck? That just seems like an odd place to go for.

I honestly have no idea about the Mareks. We had some die last year with symptoms that looked like Mareks but I never got them tested and no other chickens have showed any symptoms since I lost them, even the ones I brought in from other places that I would think would have picked it up. The ones I lost were all from the same hatchery, so lessons learned about where I get them from. I honestly forgot about this because I haven't seen it pop up since so I was assuming it was something else. Thats probably a good reason not to rehome them. You'll have to look at the video and decide but I wouldn't want to possibly spread Mareks to anyone else because I was devastated to find out that it was even a possibility. (and I lost my favorite chick) I'm sorry.

This is the original link I posted about the first one that got sick:

Yeah. I would not want to infect anyone else's birds either. I would get some more bantams of the same breed. That would probably help them out.

Under the neck is weird. Have you seen them picking on them under their necks?

I saw a bantam Wyandotte I have gently peck at ones neck but not rip anything out.
