I'm buying some nucs from a local Amish man. He advertises them as 4 frame nucs but I think its a much better deal than described. He sent me a letter requesting that I bring a hive body and 6 frames of either foundation or drawn (my choice) and a hive body. He then places his 4 frames into my hive body and lets them sit until late March. (he asked for my frames to be delivered by late February) Anyways, he runs all deeps, and I have predominately all mediums. But, I did get several deeps worth of drawn comb from an uncle as I already posted but this stuff is black as coal. I think I would get more bang for my buck if I used the old drawn comb versus foundation but I have no idea how old this stuff is. The only thing I do know is that it is from a dead out hive from last fall. (No worries of foul brood or anything, maybe a mite overload). I know we are only talking about 6 frames per hive, but I'm thinking there would be a significant difference in population between using the two. Ive searched the old posts regarding old, black brood comb and it seems to be a 50-50 mix on whether to replace or not. Any suggestions or insight would be greatly appreciated.
