We are building a new mega coop and run. I have fought gapeworm twice in my old run and while I have found no mites or evidence of mites on my chickens I do find mites under the bricks I put their feeders and waterers on if I don't spray regularly with Neem oil. What can I do treatment wise before I move them to make sure I don't move any of that with us, especially things with no egg withdrawal? Not DE, not up for discussion. I personally don't like the lung irritant warnings. I know OSHA says it is safe but they said asbestos was safe once upon a time and both of my mom's parents died from it and my mom had early stage mesothelioma but heart failure got her first.
