I, along with many other beekeeprs, noticed that in desperate situations, such as establishing swarms, the queen will lay in the cells that are only half built. Many have also noticed, that plastic with raised foundation is more acceptable to bees, then flatter kind. HSC frames are completely built up and bees accept them too after a while.
Why haven't someone come up with plastic foundation that has walls high enough for queen to immediately lay eggs in before the wax is drawn from it. Seems like we'd get a lot more frames drawn out a lot quicker with maybe 1/4" walls that with 1/8" wall depth. Yes, they will use more plastic, heck, price it higher. Certainly injection molding of plastic can handle that easily.
Has that been tried?
