Great Honey Bee documentary on Netflix "HIVE ALIVE"

My mentor is away, hoping someone has advice. Last few days there are MANY bees hanging out at front of hive. Last time I opened it (1.5 weeks ago) the brood box was pretty much empty, a few larvae and drone cells but not much else. Seems the queen was laying in the ideal super and top honey box. Wondering if the feel they're out of room? Should I move to top super to the brood box position and the emptyish brood box on top? Thanks for any advice.

Firstly noticed the tale tale sign of mumified chalky larve carcases on the landing board a week or so ago (during recent rain period). Did a hive inspection this week end and confirmed Chalk brood in brood comb . I found this site on line very helpfull and informative and thought it might benefit other newbies recognise the issue, understand the possible causes and learn how to manage the disease.

I am wondering how others manage their stickies. I have been extratcing small scale but recently scaling up a bit such that I am finding that I dont have the option to just put the freshly extracted frames back in the super they came from. I have some frames at the moment that have been cleaned by the bees after extraction but are not needed in the hive so how should I store them? Cheers Steve
