I have 2 ware hives. This is my first year. The bees are building comb and there are new eggs. They seem happy to me. I started one hive with foundation and one that has wire to keep the comb straight. The frames are langstroth design. I want to know when I should add another box? How will I know? Also should I add the new box to the bottom as per Warre method or should I add a new box to the top? How should I proceed? I am very happy with my progress so far.
