Re: Can a hive be queenless but working/foraging?
You could have a new queen that hasn't started to lay. Adding a frame of older open brood will help the morale of the colonie.
You should try one last time to find a queen before buying one otherwise your purchased queen could be killed. If you do want to buy a queen, I would still add some older open brood. And closed brood if you can.
If you want them to raise a queen add a frame of eggs and tiny "c" shaped larva.
If you decide to buy a queen you might contac:
