Sorry for photo.....these bugs are bigger than a bee. Darker too. They've shown up afternoon
The pic is a little blurry but I can make out three drones. Is that what you are speaking of?

The two bees in flight near the landing board are drones. Big eys, rounded bottoms. Make a lot of noise when they fly. If your drones are lighter, these may be visitors. Drones from other apiaries are welcomed in most hives until late summer.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
