Hi DomLazz
Here is what I am doing in preparation for a five frame nuc that I will pick up this weekend.
Brood box ready for 5 frame nuc
Bought an extra inner cover dedicated for feeding and modified
Bought jars with lids and modified lids
Place a brood box over it
Then, simply put your normal inner cover on top, then the roof.
With these 2 jars, I can put a gallon of syrup in the hive and the bees have 2 fairly good size areas to feed from.
