Whats the point in finding eggs, brood, queen, checker boarding, etc, etc,. Unless you are on a sight seeing tour all this is unnecessary. If you find eggs and/or brood, you know there is a queen. as for checker boarding, I have never done it and don't think it is necessary unless it serves a specific purpose. What you are doing is unnecessarily disturbing the bees. They put every thing where they want it, why try to change their way of doing things. The more you move things around in the hive the greater chance of injuring or killing the queen. Just my thoughts. :) d2
