I had a look in 5 hives today, was really pleased that the two splits I did have successfully mated queens and one of them has wall to wall brood on 4 out of 6 frames, my concern is them having enough food going into the June gap.
I've just looked at the two nucs I split from a double brood colony a few weeks back. Both now have laying queens and I've been keeping an eye on their stores. I've just put a feeder on top of one with a super frame of stores from the original colony. (I do like the BS Honey Poly Nucs as I've found the design is very flexible such as being able to put a whole super frame in the feeder.).
