I have six hives full and strong, some in 1 deep with 1 medium box and some in 2 medium boxes. They are close to full and I am ready to add queen excluders and honey supers to expand the hive and give them more room. Today I worked on 3 of the hives, doing just that...but quickly ran out of frames with comb and had to use new frames, some with and some without foundation. I have plenty of empty frames but no more comb. Will the bees have time to build comb and still give me honey - also, if I am stuck with combless frames is there any advantage to using the empty frames vs. frames with foundation? Any advice is appreciated.
