I do that, if they have a favorite dusting area outside it is usually under a roof of some type so it stays fairly dry and I will sneak out every so often and mix a bunch of Sevin into the loose dirt.
I had been noticing lately that I would have lice crawling on me after visiting the brooder house. I thought it was the broody chicken hens, 14 of them out there, who had the lice. I always blame the chickens first for everything.


I made dust bowls for all the pens using sand, peat, dirt, and wood ash using large plastic or rubber tubs. All the bowls in the breeder pens are under the roof, but now they have turned into nest boxes so now to do something else.
