Well, I'm trying to decide on a coup design but I have some questions first. Let say my flock gets some kind of horrible disease and I have to cull the entire group. If I have a wooden coup, is there some way of disinfecting it so it can be reused? Also, I plan on having the entire run surrounded by plants, shrubs, and vines in order to help keep the chickens cool for those 100+ degree days. Would these plants have to be removed to prevent the next batch of chickens from getting sick as well? Is there a method to disinfect the shrubs without killing the shrubs? Any thoughts or ideas would be helpful.
