I can't give you recommendations on introducing birds from different locations, but I use high quality, human food grade diatomaceous earth regularly in my chicken coup (spread over hay bedding / floor). I also spread it around where the chickens are dust bathing.
Hi, My chickens are free range in a permaculture garden. I keep a clean coop, never had an insect or parasite problem, its just precautionary. Other precautionary habits are putting a few drops of organic applecider vinegar as well as a whole clove (uncut, don't want it strong) of garlic in the hens water.
The area we put them in has never had animals in there before so that should be fine. I did check the birds over before purchasing them and they were all very healthy. And they came from very healthy farms with knowledgeable owners.
I like the idea of preventative control rather than treating the lice/worms/etc when they appear. Just out of curiousity, if I treated them as a precaution for worms and it turned out they do have them and they are in their permanent home, would I have to strip the pen after a few days to avoid reinfection?
