Re: Queen Mating Question
As to mating, generally they will intermate freely. I do recall reading a study once showing evidence that certain queens may preferentially mate with certain drones, but this was not a rule just a tendency. For your own mating you should regard it as a free for all, first come first served!!
Italian bees are pretty forgiving as to which queen they will accept. Most bees will accept most queens however we did used to have more trouble getting AMM to accept italian than italian to accept italian.
I've read that africanised bees can be hard to successfully requeen with a different breed.
