We're in the middle of blackberry right now (I'm told it's our major flow for the year) so I left my topbar hive alone hoping that they'd pack away stores (first year hive from package). Every few days I'd check through the widow and they've been drawing out fresh comb so I figured it was all honey. I checked today and it looks like every bar is brood! thats half of a 4' long TBH full of brood with not a single cell of capped honey. should I be worried? Also there is lot of it is drone comb, and they have been putting some nectar in vacant cells in the brood area (is that what people call back filling?). Over all there is uncapped nectar on every bar so they won't starve right away.
Is there anything I can or should do? Should I expect to have to feed syrup in the fall?
