You can tell that I am new by my questions. I was wondering if it was natural, on hot days, for the bees to gather out on the bottom board instead of going inside the hive. Some days the bottom board and brood boxes are covered with bees. My hive is located in dappled shade throughout the day, but it has been really hot and humid this summer. I believe I heard someone say to move the top brood box a little to let some air in the back. Is this true? Wouldn't that allow rain to enter and cause the wood to rot?
