Huh, that's interesting. We did just add a deep to the hive - a 2nd brood chamber as this is a new Nuc. The nuc came with 5 grungy old frames, which were full of capped brood and are basically the heart of the brood chamber. I wanted to pull those frames out, but was unwilling to sacrifice the beautiful brood there. It was also the only drawn comb in the hive to start, though they've been working on remedying that. Come to think of it, there was one old frame that was positively full of honey - the only one in the hive - and I moved it to that side of the brood chamber into slot 10 and moved an empty frame that hadn't been drawn out yet closer to the brood chamber to encourage them to draw it out. Wonder if they ate the honey and are cleaning that frame up? Does that sound plausible?
