I have successfully reared some queens to replace my 2 old queens and have now decided which ones I want to use (based only on size and sealed brood pattern. These queens are in 5 frame nucs which are now as full of brood as possible. I have marked them.

My question is ... what is the best way of introducing these queens to 2 quite strong colonies, one of which has a queen that is I think very small, as I have never seen her. Should I just catch the 2 new queens and introduce them is a cage in a standard way or is there a way of combining with the nucs??

Thanks for the help from members that has enabled me to get to this position. I managed to get 5 successfully mated queens out of 6 nucs ... beginners luck?
