So I have two hives from last year and started a couple new ones from packages 2 weeks ago the hives from last year wintered in two 8 frame mediums which is what I am using for everything they both have completely drawn comb so I added a box to each with foundation to get drawn out and hopefully help with swarming now they are laying and working the 4 middle frames in box 1 and 2 not doing anything on the rest is this normal or do they have to much room should I move them around or what
