Seeking some advice on a hive that is not moving into the super.
Brood box is full and everything appears to be okay, however the hive has not moved into the super which has been on the hive for six months.
The super is 10 frame, plastic frames with real foundation. We have a queen excluder between the brood and super.
Hive entrance faces north.
Our other hive which we started at the same time as this hive is now onto its second super (flow hive) and it doing really well. We have even managed to create another nuc from this hive.
Any ideas what could be wrong with our hive?
