I wait until the first pips before I cut the rest! This way I know that they are ready! Since you don't have experience cutting then I would wait until day 60 or the first one pips, whichever comes first! This way you still have two days for them to come out while your home. Experienced breeders like Rich cut earlier because they know how to take care of them after and they know the signs to watch out for! Good luck! Not an easy decision!!!
