Thanks for that reply, Allen. Never heard about the North-South idea. My boxes are oriented with the entrance facing east, to get morning sun on them.
And yes I have lots of irregular comb, especially on newly drawn foundation. They like to make blobs rather than even sheets of comb, and make them thick so it intrudes into the frame next to it.
I always wonder how much to trim and groom those frames. One box I have came from a captured swarm and has no foundation. The combs are stuck together and hard or impossible to pull out and inspect.
What do you do with that?
