Hi, I currently have KTBHs, but I'm considering getting some Warres next year. My concern is that from everything I've read, the bars in a Warre are supposed to be nailed into place, which means they are not movable and probably not legal in my state. However, I've also seen videos of people inspecting Warres and they were taking the bars out. In these hives, how does one maintain proper spacing between the bars? Sorry if this is an idiotic question, but I'm trying to figure out how the bars work.
