My starter hive, a common design, well ventilated as wire on bottom as well as sides.
This 5 frame nuc box is filled with nurse bees as I shake at least 6-7 frames of bees into the nuc. Older bees are allowed to fly off, I just want nurse bees. Then I add 2 frames of capped brood and 2 frames of nectar and pollen. A soaked sponge provides water. Mr. Bush has a video more detailed on YouTube.
This box is used for 48 hours total. First 24 hours the nurse bee fill up the Royal Jelly glands. Then I add grafted larva and remove the next 24 hrs [total 48 hr] later I move to the finisher colony. This works well for a small time hobbyist beekeeper, Me, as I graft 16 larva at a time. Be sure there is no eggs or young larva on frames, just capped brood, pollen, and nectar.
