Possibly mareks? Or is it cocci? Or something else?

It sounds to me that they are eating something . I would start a new bag of feed. And check around for anything that could poison them, or anything that could give them botulism. I had 2 hens eat a dead mouse once, and they both died overnight. I didn't see them eat it, but I went to toss the trap and the mouse was gone.

And I guess I would also put corrid in their water.

Do you think it could be under nourishment? I take layer feed and cut it in half with corn since roosters dont need nearly as much protein. And do you think unripe mulberries could poison them? Though my hens are eating them and havent noticed my roosters eating them at all. Or even im thinking theres a walnut tree thats been there for ages could this be hurting the iny way? In the soil or anything?

I'm not sure what plants are dangerous. I don't think it's malnourishment, but you should feed all feed and corn is a snack. I know corn can carry some type of spore. Feed can go bad. I don't know if they have been thru new feed since this happened.

Can they get to poison? Or poisoned rodents? Look around your yard. Sit out there every day and watch their behavior.
