Yep, I do know about the inbreeding thing. And in the past I have had two hives that were just so darn mean, different years, that I tried to sulfur kill them, and that only worked part way. So I got out the shop vac and sucked them all up. What an awful experience mean hives are!
Anyway, back to drones.
So I have 4 hives this year, all of them in my backyard. If there arent any other drones in the area, the chances are that she will mate with some of her drone stock plus drones from the other 3 hives.... right?
