Yesterday I pulled out the SBB tray to take a look. I found the usual lines of capping debris, and right in the middle of these lines, a small pool of water, maybe 1" in diameter. Any idea where this may have come from, or if there is anything I may need to do about it? Hive is 1 deep + 1 shallow. Went into winter on the small side, but packed pretty full of honey. I wrap with tar paper, so the tray area is protected from blowing snow. It's been too cold here to risk a peek under the lid.
