I’ve only have one 5-frame deep nuc and it is wrapped in insulation and tar paper. It feels a bit light to me (no scale). The bees are flying on warm days, and I’ve put sugar bricks on my other hives. Should I tear apart the insulation on the nuc and give them a brick or patty? I don’t have a shim for the nuc and would need to make one. Then should I wrap it back up?
