Too late for a medium super?
Located in Central NY. I have a hive with 2 deeps. Bottom is full of Brood, top is fully drawn out comb. A ton of bees. Im curious about adding a medium honey super (with our without QE) so they have more space to work, or is it too late in the season? My thought is that they will take this time to focus on building brood/honey in the upper deep. Would extra space now be too much space, since the nights are starting to get cold? Or will they work fast enough to get that extra medium super filled by winter? Thanks.
