ok, so i pulled 5 frames from a hive ( two brood and two stores, and one drawn comb, mostly empty ) and slapped them into a nuc box for the time being. mind you, my eyes aren't that good so i can't see eggs or really small larva, but i grabbed two frames that looked like they had a lot of larva and not a lot of capped brood, lots of nurse bees on the frames. if they have any eggs or larva of the appropriate age they will do exactly as i hoped, but what if they don't. could i put these frames back into the original hive with the bees on them or would there be a fight ? should i shake the bees off and just replace the frames ? what i really want is a successful split though. i know i should probably just wait and see, but what else can i do if this fails ? thanks in advance.
