Hi All - Despite keeping my coop very clean - somehow my chickens got lice. I noticed them on my big white rooster and his mate. I assume that means everyone has them. I just can't understand it. I rake the ran, remove old feathers, turn the bedding and scrape the roosts EVERY DAY! Anyway, I read about treatment and went with the Permethrin 10 for poultry. I stripped and powerwashed the coop, scraped and scrubbed the roosts, floors and walls. I couldn't get boiling water to pour on the walls and floors. I hoped the powerwashing would do. After that was done, I sprayed the walls, floors and any crevices I could get to with the mixture of permethrin and water. Once it was dry I put DE down and I bought fresh straw for their new bedding. Then - I dipped all the chickens (27 of them) in the solution prescribed by the label and let them dry in the sun. Finally - I took what was left in the bucket of dip/water solution and raked it through the run and sprinkled DE in the run and let the chickies rake that through for me. It took me 6 hours to do all this! Wish aI took a picture of what I looked like after all this! It says I have to treat them again in 2 weeks - so I bought powder for that. Do you think this will do it? Does anyone have advice?
