Jeff, most moisture conditions are not in the dead of winter. It happens in the fall and spring when the conditions are right. The conditions you have allow your hives to make it through without a problem. Not everyone will have that luxury. What you don't know is would you have had 26 out of 26 make it through this winter if you did not use the chip bed?

In this instance I am going to side with the commercial operators moving thousands of hives all over the country and not using the chip bed method of overwintering. In my line of reasoning it has zero value. You obviously feel completely different otherwise you wouldn't do it. That's OK. Do what you like.

John would like to know why it didn't work for him. I gave my reasoning what is yours?
