I'm planning to prime all the wood on my coop with Kilz 2 primer both inside and outside. Then paint a semi-gloss coat over that both inside and outside the coop. I'm hoping this would prevent red mites from being able the hide in the wood during the day. Also I plan to get cedar branches and use them as roost in side my coop. I will also plan on having Diatomacious Earth in their dust bathing sand/dirt (most likely i will use sand) With regular cleaning included in the regimen as well.
