I purchased three hives that have sat without bees in my neighbors shed for the past few years. The hives consist of two 10-frame deep boxes, two 10-frame medium boxes, hive-top feeder, solid base board and hive cover. The frames all have "new" unused foundations that are mixed between the black and yellow looking foundations. Other than some dust and cobwebs the hives look pretty clean. Is there anything I need to do with these hives before introducing my bees in a few weeks? Want to make sure I am setting things up right for my new visitors coming soon. Any help you can provide is greatly appreciated.
