We shift 200 miles to almonds, but most of our honey is collected within 100 miles of home.
If there is a good flow then one trip to put empty super and bee escape, then back next day to bring home the super of honey. Our extraction is done at home.
Not all hives fill at the same pace (wish they would) and so you are back next week to harvest the rest. We run groups of 50 hives but there may be 2 groups at a site if flow is good enough.
Back to one brood box, our good queens will fill a frame totally with brood, two teaspoons of honey in the top corners, and will fill 6 frames like this, even will layout the insides of frames 1 and 8. Very rarely will they lay on the outside of 1 and 8.
These are our best queens where others will use 3/4 or 2/3 of the frame for brood and store honey in the balance. These are not usually our best hives due to not enough bees. Whether these queens would perform better with 2 brood boxes and can have honey around the brood would be interesting.
