Shingles are windbreaks.
I'll be moving my full hives onto the ladder next spring. When I started with two hives, I separated them by 10 feet. I've since learned they do not have to be that far apart. The ladder is on blocks, and I may need a "brace " in the middle. I'll use simple "scissor jack" for that.
I've modified my beekeeping practices after attending seminars by Michael Bush and Michael Palmer. I'm a little more "laid back" now. "Hey! Whatever works,... and is easy,.... works."
