Elizabeth told us about bees building drone foundation immediately adjacent to Plasticell foundation, rather than "drawing" the Plasticell. Bob Darrell, said he thought the difficulty was a combination of bees space and bees not liking the plastic...I agree. If you want this again, Elizabeth, just continue to do as you did last year. It will probably produce the same result...but may not. In my experience, bees will properly draw Pierco only when given a full super of undrawn Pierco foundation. Then they will do fine. Anything less than a full super and you are likely to have problems. Far better, in my opinion, is the Dadant beeswax coated Plasticell.
