Don't ever put the lid on without filling up the hive body with frames!!!
I added a new deep hive body on top with 10 frames of foundation. I want to encourage them to move out of that filled body ASAP because it's really hard for me to tell what's going on inside, and I don't want them to swarm. Have to get them out of this hive box so I can clean it out. Makes me sad that I can't pull out frames and look!
