Hi all

If you are trying to introduce queens with a marked genetic difference to
the existing workers you have a choice:-

 you can do it quick and easy and lose anywhere between 0 and 100%.

Or you can spend time and effort and achieve your objective with (so far)
100% reliability.

Your Col. Sanders showed the way and a couple of English guys that are often
faced with introducing 'exotic' strains of queen have refined the method.

It is called the Steve Taber/John Dews/Albert Knight method and you can see
the details on the page about 2/3rds the way down
http://website.lineone.net/~dave.cushman/queenintro.html

There are many other methods and many drawings of the different cages on
this rather long page.
