I'm in a peculiarly low brood situation due to repeated losses of queens due to what seems to be damage in transit.
I have a couple hives that have LW. Normally I'd do the frame of brood a week approach, or shake out and let some enter new hives and some return to original location with a queen right hive there.
Because I'm low in brood the first is difficult (tried to get some from a friend, but he just made up a # of medium nucs and is light on spare brood) and the now queen right hives are a bit fragile so worried about returning bees still killing the queens.
If I put a queenright hive over a LW hive with harware cloth between them, will the brood pheremones pass through enough to revert the LW to workers over a few weeks, as well as let the hive acclimate to the smell of the queen? Then can just pull the cloth after 2 1/2 to 3 weeks.
