I have: two hives with three medium brood supers all on regular plasticell.
When I add 4.9, should I checkerboard it with the plasticell or pull an entire super and add an entire super of 4.9?
Is drone cell size the same for small bees and large bees? In other words, I have some drone foundation, will the bees use it for drones or not?
Maybe I missed this somewhere: When treating with Oxallic acid, does the queen need to be pulled? Is it okay to treat with brood on? Is it okay to treat with honey supers on?
