Hey Parksguyy
Great seeing a neighbour on here
I'm also using drone frames as part as my IPM but mine are filled with honey

It might have to do with their position within the colony in at #3.
I'm going to attend the Lanark gathering as well - looking forward to meeting you and everyone else who will be there. The hosts are pretty awesome people!
I'll look into reversing the bottom deeps with the tops - that sounds pretty logical.
