Is It Time to Add Another Hive Body?

When your foundation is all drawn out and the queen has filled most empty cells with eggs, larvae or pupa, you may need to add your second hive body. I like to put the additional hive body on the top. If you started with two boxes in the beginning of the season, you will want to swap positions (putting the bottom on the top and the top box on the bottom). I will probably add my second boxes in a week to 10 days.
