Rearing Queens and breeding bees - A Practical Manual of Beekeeping - page 234

Advantages : This method has several advantages. It can be used to produce queens and
as a swarm-control method. Similarly, there is no need to find the queen although,
after day two, you will know which half she is in. This method can also be employed to
increase your stocks, if necessary.
Disadvantages : Although not essential, another apiary site is an advantage. More work,
time and care are also involved. It is important to note that, in both variations, the
beekeeper is forcing the colony to raise queens from what were originally worker cells
under 'emergency' conditions. Research has shown that queens produced in this way
may, on average, be inferior.
The Miller method
(Larval transfer not necessary.) This a very easy, controllable way of rearing queens.
First, take a frame of foundation and trim this to form triangular shapes, as shown in
Figure 29. Put this frame into a strong nucleus hive that contains a queen, plenty of bees
and frames of brood and honey.
