I have 6 hives, half are 2 deep and the other half are 1 deep (splits and swarms). I did a full inspection on all of them today and found fantastic brood patterns in all the hives, totally filling 7/8 frames out of 10, but unfortunately almost no honey stored. Clearly, they are going to need some food to make it through winter. Is it too late in the season to add another deep so the hives have room to store enough honey to (hopefully) make it through the winter? I'm under the impression that if I feed them 1:1 syrup, they'll build out the comb faster, as most of the frames will be just be foundation. Then I'll switch to 2:1 syrup. How late in your fall season do you feed your 2:1 syrup?
September tends to stay in the 70-80 range where I'm at and October has been warm in the past as well. I'm worried that by adding another deep, it'll give them too much space when they cluster.
I'm also curious about keeping 3 deep hives vs just 2, but I might have left it too late to expand.
Thoughts? Or am I overthinking it and should just add the **** deeps already.
