So I've had a few hours to mull this over and I've come to a few conclusions. (How accurate they are is anybody's guess!)
It seems like however we choose to manage our hives--treat, don't treat, change out the foundation, use it forever, etc--the results are basically the same. So I coming away from this survey thinking that: 1. We should do whatever feels comfortable knowing that, statistically anyhow, nobody is getting any better results with their way than we are with ours. 2. The success or failure of a hive STILL depends mostly on the skill of the beekeeper in recognizing what is going on in the hive and around it, interpreting what that means to the hive, and being able to implement whatever the hive needs to survive both short term and long term. And 3. Our skill improves as we go along. The more we learn, the better we get and the more of our hives get to survive our education!
As always, JMO
