Finsky is wrong..
Heh, heh, that depends waht you wait for queens quality. If everything suits it is same what you do. :P
It seems that you have not read any "queen raising" book.
Yes I know that even one frame of bees are able to raise queen like bug.
I have raised queens 40 years.
And one mistake is to let bees raise theirs own eggs to queen. In that case there are no selection to use good stock.
The quality of queens are the most critical matter in beekeeping. Yes, I am right what ever you say. :P To get egg laying queen from small larva it takes 20-30 days. During that time byed queen produces one cycle of bees from combs.
It is just wasting of time that 4 frame nucs raises it's own queens.
If someone needs one queen, there is no reason to raise his own. If you need 10-20 queens, you need a good mother queen. And so on...
Just now I raise queens in hives which try to swarm. I get 10 high quality queen when I change larvae in swarming cells.
