Just a quick look in the 2 congested hives today. Hive 2 seemed to be ok, a small amount of nectar was being stored in the super but no eggs or brood. The main brood nest had expanded slighty. Hopefully they will be ok for space now. I will move the super under the brood box later on in the autumn.
Hive 3 was also putting nectar in the super. In the brood box the queen had resumed laying but 1 capped queen cell was found. As I suspect the queen cells are being produced due to the previous congestion I removed this one again. I will check again in a week and hope the bees will of lost the desire to swarm.
