DE is very bad on the lungs, both yours, and the chickens. Wood ash works well, but is very harsh on the skin.

It was probably the wood ash.How long did the coop have the mites?
We clean coop's often and put new pine shavings down. ...and in between changes we scatter DE on the floor.
We use food grade DE and once a quarter routinely add 2 to 3 cups to the one foot tall dust barrel ..... which has fresh wood ashes and dirt.... for dusting.
Occasionally, we find a bird with mites and will literally dust it with DE under wings and generally all over rubbing against the feather layers. (old hair blowers work wonders at this time....however because we drop DE in the intake for distribution...they don't last long...we do this outside and wear mask).
The program seems to work.
I buried the hen right away...that was a couple weeks ago. I will have to look at the others. I have not had a moment to spare....I am a Teacher and I have 13 dogs, more cats, the 11 chickens and have spent the last 4 days prepping for a major storm and freeze in the Houston area....along with tending to a very sick cat that I had to put to sleep this week. My life has been hell. But I have tried looking and I don't see any bugs...but I have about 200 bites on my body....it is horrific. I actually slathered myself in almond oil and an anti bug essential oil mix last night and finally got a night's sleep without scratching all night long from the new bites. I also have the 2 chickens that live in the office room next to my bedroom and won't be able to get them outside till Saturday after the the freezing temps and snow have stopped. I have 2 washing machines that have been going nonstop since yesterday. Can the northern fowl mites or the red mites live off of my cats or dogs? I do see red dots that do not move....even bought a magnifying glass...I think those are just flea droppings off the cats. We have fleas even with monthly flea treatments. The other issue is there are 2 oppossums that live under my house and they they have broken into the HVAC ducts as I caught one in the house one morning, eating the cat food. Can the mites live on Oppossums? I hate the ducts in these double wides as they have a fiberglass internal lining that allows fleas and what not to live in the material. I am trying to research how to replace them with something else that animals can not chew thru.Did you try any of the things I posted here? https://www.backyardchickens.com/threads/evil-chicken-mites.1354517/#post-22342505
Did you check the deceased hen (or the rest of the flock, for that matter) for mites? If you can confirm the birds have mites, then at least you'll know what you need to treat for. The birds will need to also be treated concurrently.
Count on vacuuming a lot, and washing/drying sheets. If these are Northern fowl mites you won't see them, but as they can't survive off human blood they'll die off gradually. Red mites can live longer, but you could try checking crevices near where the kennel sits. You're looking for tiny red dots that move when their hiding spot is disturbed.
I wouldn't know where to put the tape as I can't see the darn things...LOL. Iam also worried about using the chemicals in the house because of the cats and me. Was hoping someone had run into this issue before....been washing bedding and clothing nonstop. Have a gazillion bites all over my body.If you could get a few on a piece of tape you may be able to identify what they are so you can treat accordingly. Permethrin is my recommendation but I have never had them in my house.

Yah, I have thought about that. I use it with the dogs that I rescue that have demodetic mange mites....but that seems to be mites that burrow and live under the skin. Iam assuming these mites just live externally and bite me.
And I have lyme disease....which are internal parasites, so it might be beneficial. Problem is, Houston is pretty much shut down this entire week due to a historic storm of freezing rain, snow, freezing temps....we are all in survival mode, so no doctor trips this week.Doesn't matter, it's systemic. Studies have shown it will even knock down bedbugs (though not completely), and those bugs are hard to kill!
And just for good measure, it will protect you from COVID for a couple weeks. What's not to like?
