I have not had mites but it may be because I use the white mite powder I sprinkle it everywhere in there coop bedding and walls floor and all around the area so far so good it's espeacialy for chickens and Ducks. It's easy to buy on Amazon or Ebay.
Thank you for sharing your work it's really good i love the coloured glass effect it looks professional im impressed and looks good enough to live in we made a chicken duck house I'll post it.
Can I grow a purple fountain ornamental grass plant in and around my chickens and Ducks I know this plant is not poisonous to cats so I'm guessing that it's fine.
