Not difficult. Take the eggs out of the fridge as early as possible (not later then March). They go through the first instars rapidly, but the final instar takes much longer. Ready to pupate within 7 to 8 weeks. Keep dry, clean, at room temperature in well ventilated plastic containers when young and in a netted cage when they have reached the final instar.
