Thank you for all your comments. And great photos.
Yep, I certainly had queen cells. I eventually tried to split the hive and now have two hives but not convinced I have a queen in either!
Good news is they haven't swarmed!
How soon do new queens leave the hive and for how long, when they fly to mate?
What is the longest period after an egg is laid can it turn into an emergency queen cell?
Just trying to decide what to do if there are no queens.
