One of my new hives is a nuc that came with 5 very full frames of mixed vintage and foundation (some crimp wire, some plasticell). I put undrawn crimp wire foundation in for the other 5. They are in the second deep now and have built out that nicely. HOWEVER, when I finally got around to looking back at the bottom deep, I find that the nuc frames are a real mess - some of them half eaten back to the plastic, one of the wires in another has sprung, etc. I do not have drawn comb since I'm brand new to this, but I do have some nice clean crimp wire foundation and frames I could put in. When is the best time to do this and should I worry if the old stuff has patches of honey or brood on it??
