I pulled a frame out of one of my big colonies that had 5 capped swarm cells on it with little to no other brood. I stuck it and a frame of honey/pollen in my queen castle. I waited around 12 +/- days to check on them. I found four cells chewed opened from the side. The remaining cell had not yet emerged. Upon closer inspection, I found one of the chewed cells had 5-6 eggs in the bottom.
Is this a problem with a laying worker? Will a laying worker destroy queen cells? Since my parent hive hasn't swarmed (marked queen still present), and if the last queen cell isn't successful, can I return these bees back to the parent hive?
I really didn't do this for increase. Just to control swarming of the parent hive and to safeguard against my parent hive being queenless if they did swarm. Thanks, for your advice.
