I am impressed with Layens hive beekeeping.
They are easy to manage, and I like the deeper frames. In my long langstroths the brood nest gets elongated like a stretched out, long thin football. That means brood can be in 20 out of the 30 total frames in the box.
The queen can't lay up upward, because it's a long hive. I don't want to use an excluder to exclude her into fewer frames (like single brood box beekeeping), because that means frequent monitoring for swarm cells.
So, these Layens have piqued my interest.
However, the 14 frame Layens are too small.
15 frame Layens= 1 deep & 1 Medium Langstroth box
30 frame deep long lang= 1 deep & 2.75 med
25 frame Layens= 1 deep & 3.5 med.
28 frame Layens= 1 deep & 4 med
I plan on building two of the 28 frame Layens this summer/fall, or however long I can make them using 4 feet standard lumber and plywood.
