Re: Icicles *inside* the hive!
Is the bottom board solid or screened??
What size is the opening in the bottom entrance reducer??
It would appear there is not enough ventilation and what is restricting it?
Can you open a 1 3/4 slot in the lips of the inner cover? I open it and invert the cover to give a 3/8 by 1 3/4 on the under side that provides an upper entrance and exhaust port. I also have a 3/4 round hole in a feeder shim just above frames. Do get some frost build up on the upper entrance and round hole and I rim them out if much frost is building up.
If you always do what you always did, you'll always get what you always got!
