How often can one rob the brood nest? I have one strong hive and need for brood but feel bad opening it up every other week. Do you all keep a hive going 'just' for brood during the season or rotate from different hives or???? What is the best way to have brood for your needs (Trap outs, queenless hives) with the minimum disturbance; especially to strong producing hives. Not to mention having to remove the honey supers first before getting down to that brood nest just to see if there is enough.....

thanks!
