I did my first cut out a week ago, and believe me, when there are bees going everywhere and comb all over the place, the last thing I was worried about was trying not to cut brood :lol: I had a peak in the hive yesterday and they have already made some repairs and started throwing out rubber bands.
Initially I felt bad about cutting the brood, but as schawee says, it's more about saving the colony than indivdual bees.
