I'm so sorry!
Years ago I lost three nice hens before I figured it out, and it was mites. Awful!
Get the permethrin spray concentrate, it's easier to use and less expensive than the dust.
Spray the coop, walls, roosts, everywhere, and every bird, at night while they are roosting. Wear gloves, long sleeves, and at least a N95 dust mask!!! Do it soonest, rather than waiting to clean out the coop, or at least spray all the birds, walls, etc.
You need to clean out the bedding, and then powder the floor before adding new bedding.
