Aren't there only two cell sizes in a hive? I'm a little confused - this past weekend I was speaking with a beekeeper who told me he had deep frames which have be drawn and were used in his deep honey supers last year. Because of the weight of full deep honey frames he's decided to go with mediums and now has these deep drawn empty frames stored in his honey house. He told me I wouldn't be able to use them in my deep brood nest because the cells from a brood nest aren't the same as cells built for honey. Is this correct? I was hoping to take these off his hands to use in my brood chambers next spring but he said it wouldn't work.
