Nucs are going OK with 1-1 1/2 frames of brood and some older brood starting to emerge.
Today I topped up syrup and added another 1/2 of a MegaBee pattie.
Brood area is increasing in all the hives. Nuc #1 has some dodgy looking capping so I have inspected those and a few more cells. All is OK so far but I will remain alert the this in future inspections.
