I am looking for technical and practical information on a queen
breeding system attributed to Farrar. I have only heard anecdotal
stories about the system. Evidently the system excludes two breeder
queens (using custom-fashioned parts cut from normal queen
excluders) to two frames each in a brood chamber. The larvae are
transferred from these combs. The bees are led to believe something
is wrong with their queen(s) and will thus start queen cells. The
system would be attractive to breeding scutellata, which "prefer"
manipulation in very large colonies.

Thanking you in advance
