Re: BetterComb Experience, Anyone?
Wendy, I would file this under "that's interesting", and move on. Bees do three things really well, make bees, make honey, and make bees wax. To do these things, they need a cavity to call home, a prolific queen with healthy bees, and resources in the form of carbohydrates and protein. They will take it from there. If you are not seeing a lot of comb in your hives yet, it is because the bees do not need it. Adding in synthetic comb is unliky to have any effect except to lighten your wallet. Spend the money on a good feeder, I like the styrofoam one that Betterbee sells, get a feeding shim for each hive and a package of Ultrabee pollen patties. Feed the bees syrup, and patty if they will take it, and they will reward you with more bees and drawn comb. I prefer foundationless frames for the brood nest so somebody else's potentially contaminated wax is not a concern.
As Brother Adam said, "listen to the bees and let them guide you".
The lack of new comb is telling you something.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
