Hi
I got my first hive last year, i had 2 brood boxes and put a honey super on about a month ago with a queen excluder.
And my hive still swarmed, I have since removed the queen excluder and moved a few frames around to see how it goes.
The swarm happened about 2 weeks ago with about the first decent day we have had since all the rain, I have only entered the hive once since , will let them be for a another week, there where quite a lot of queen cells in there and I moved them into the top box, not sure if that is the done thing, we will see.
I do have a look at the hive most days from the outside and bees seem happy enough and doing what they do.
