Trying queen rearing this year, probably will use a four frame medium for the mating nuc, other than putting in a frame of honey and pollen, does it help to put in a little brood also? If so, does it matter whether it's sealed brood or open brood? About how many bees can I get by with when I stock the nuc? After stocking nuc but before inserting queen cell, should the bees be screened in for a day? What about after the cell is put in, can you confine them for a couple days to make sure they stay. Thanks, John.
