Re: Rooftop hive in Chicago
The bees don't care about the box, it's not about the box, it is about the bees inside the box. Get good bees.
The boxes, get for your convenience. I'd reccommend all 8 frame medium boxes. They are lighter, and 2 inches less wide, so center of gravity is closer to your body therefore easier to lift and carry. You're managing these with a ladder remember. A beehive or 2 is not worth a life of agony if you fall and live.
I've been keeping a few hives for the past 20-25 years, and no longer treatment free as I got tired of the losses.
