Bizzybeehoney and Mark. Welcome to our forum, this will be a great place for you to learn, ask your questions, tell us of your experiences, it is a great place to spend some wonderful time.
Mark you got your nuc on May 31. You will not need to add a brood box for awhile yet. Don't worry too much about adding that brood box yet. As you become familiar with the forums you will find that there are other places to ask your questions. They will get much more noticed if you go to the beekeeping part. This little forum here is mostly for introducing yourself, to tell us about you, and do that thing, we love to hear about what new members are up to, this means you too, Bizzybeehoney, when you have time, tell us your stories, we are a curious and nosey bunch, hee, hee. Have that most beautiful, wonderfully awesome day, Cindi
