Both those hives seem to have settled down. The first swarm to arrive - now Hive 6 - has a broodbox brimming with bees, and has reached the stage where its temper is beginning to show. The bigger the colony, the more older bees there are going to be in the hive, and these are the ones that sting. Yesterday they got up my arms and under my veil - a habit I loathe - and stung, so I won't be raising queens off that one unless it turns out to be a one-off. They don't have any drone cells that I can find; swarms often don't produce many in their first year for some reason.
The other one - Hive 4 - hasn't had so much time to build up, but it does have drone cells appearing. It's got a slightly bigger broodnest; 8 frames as opposed to 7. In a couple of weeks I should be able to start raising queens.
The wren's bringing beakfuls of insects into the shed, so the eggs have to have hatched.
