Depends upon the foundation. If plastic, it can be very tricky cutting them off. If wax, then its pretty easy - just carefully cut them out an place them in mating nucs. I've used screen wire cages with plastic foundation, but then you're faced with introducing virgins. There's been plenty of discussion on introducing virgins, so please search to find what works best. Read up ASAP, as some techniques suggest a 3-day delay prior to introduction. Probably would place cages or cut out cells this Wednesday, which should be day 14.
