Re: Do you use an inner cover or not and why
I started my first 20 or so hives using telescoping covers with an inner cover. My only complaint is price if I purchase them or time if I build them. I've gone to migratory for these reasons. After using the migratory with the "cleats" on front and back for a couple seasons I started using 3/4" plywood the same dimension as the box. I like this by far for its simplicity. In the winter I run a 3/4" spacer under it with a 1" opening for ventilation and alternate entrance should they plug the bottom with dead bees. I haven't seen a difference in wintering success between the two styles. For feeding I have seperate covers that have a hole for the jar lid and use an empty deep on top with the cover.
Beekeeper? Shoot, my bees keep me!
