A few years ago Ted K and I entered into a wager, that within 15 years even commercial beekeepers would be treatment free. In light of some comments made on the "unwritten rules..." thread about the impact of treatments on queens, I was wondering:

Are any commercial beekeepers experimenting with an apiary or so the possibilities of going treatment free? I realize it is an economic impossibility to risk your whole operation, but is anyone testing the possibilities with a small portion of your operation?
