Adam - Very interesting - this was our original thought, 10 days ago, that they were getting over crowded so we added a super, then didn't know what to fill that with so added some frames. A few days later we decided this was a bad idea as winter was coming so we took it all off again and confined them to the brood box ( and the sugar syrup feeder) as we thought they would then fill the last couple of frames with honey from the heather and have good stock for winter. They have 11 frames and a dummy. As newbies we don't have any more kit or boxes to move them too and as I guess the queen will stop laying soon, the numbers will go down. Who knows whats for the best!
We got the nuc and the queen, who is a 2010 queen, white marker, about 7 weeks ago so maybe her mature daughters are playing up. I shall feed them all quietly this evening and then perhaps have another look in the brood box on Monday if the weather improves.
