Right now,one hive consisting of two 10 frame deeps of an Ohio swarm of muttsutts.
Actually, I have a piece of 1-1/2" insulation foam on the very top of the outer cover on the outside of it and strapped down with a brick and rachet strap. A beekeeper of 40 years in my area says that is what he does so I am trying it. I do not have insulation on the underside of the top cover, however, the top cover rests on a quilt box with a moister board. With the daytime temperatures that we have had this past month, I fear I may have jumped the gun to early on the Bee Cozy wrap.2" of foam under the top cover?
