TimLa. Welcome to our forum, it is great to have new members. Good luck with hiving your package, you can keep them for a few days in a dark room, that won't hurt them one little bit, just spray the screen with sugar water to ensure that they have some food.
You have found the right place to spend some wonderful time. If you have questions they will be answered, and always remember, when you have a question, ask it, never concern yourself with any thoughts that it may be a dumb question, there is no such thing. We were all once beginning beekeepers, and we asked questions too. Have the best of this wonderful day, love our life we live. Cindi
