Nasty buggers 🤮 Give the chicks and the coop a good dusting of diatomaceous earth!

Agree with the others posting. Diatomaceous earth is amazing stuff

Try Ivermectin https://rusticrootsliving.com/best-treatment-for-chicken-mites/

Dust the chickens with diatomaceous earth if you don't want to use pesticides. Trying to think of the natural pesticide I used to use, it was some plant extract, can't remember the name, but it would both prevent and treat flies mites ticks etc. Something you spread around the coop.
