A nuc is a small colony of worker honeybees and their queen.  We use good quality Italian honeybees for our nucs as they are best adapted to our central Texas climate. It contains a total of 5 deep frames. 3 of those will have bees and brood (baby bees) on them.  1 frame will have food stores such as honey and pollen.  The last frame is normally a drawn frame that is empty of for the bees to expand.  All of this is contained in an Ez temporary plastic transport box.
