I have 10 hives and have had probably 20 over the last 5 years. I have my entrance wide open. Every hive I've ever had always come and go from the far left side of the entrance. Probably using 2-3" of the entrance. I've always noticed that. But this one swarm I got a few months ago uses the far right side of the entrance to come and go. Just an observation.

Hey look a penny.
