In all my years of beekeeping and taking and helping with classes, I still have yet to see actual teaching frames of a healthy populated double deep ( or a deep and medium) style hive. There are some avalible, I think I got my set from betterbee? There are 2 sets in print that I know of, one is a healthy hive , the other is a trouble shooting set Charles *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
