I have one hive that I am almost positive is queenless with laying workers. The hive is about one/sixth drones which look small. I saw scattered drone brood but no worker brood. It is a 2 story that otherwise seems healthy with plenty of stores. They were gentle, were making wax and seemed generally organized.
I would prefer to requeen rather than scatter the contents to other hives. If I give them a frame of eggs, will they raise a queen or do they think they are not queenless since they have a laying worker? Can I force them to raise a queen?
Open brood is suppose to stop the worker from laying. So you might give them open brood frame now and see what happens and then another frame a few day later if they haven't started queen cells yet.

If you don't find your answer at MB's site you haven't read it very well. It says just about everything you need to know on requeening a laying worker hive.
Thanks for the info. Michael Bush's site is very thorough and comprehensive.
