I said *might be* and YMMV i amending my original number, which is prolly closer to real world since it yields a 5% to 7% loss. In practice I do not have enough measurements to prove anything, but I do know that wintering loss is very low when good hives are combined by a knowledgeable crew or in two-queen colonies that are wintered with the excluder pulled -- and in my area. I know nothing about generalities, only the specific cases I observed. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
