Looking for a way to boost your colony; add a brood frame with nurse bees. Make your Nuc a full sized colony with the addition of more brood frames. Each frame has at-least 65% coverage of brood on both sides of the frame. Remember 1 frame of brood is equivalent to 3 frames of bees in your colony. We try to give capped larva with each brood frame so that you can see the results to your addition as quickly as possible.
