reinbeau, it seems to me that all the big guys use "HFC syrup" if they need to feed. I think they do this because they can pump it directly in to the feeders. No heating the water, ect. So it can't be all bad, can it!?
I did check the price of corn syrup in the store and find it much more expensive, compared to sugar, probably because they sell a lot more sugar than corn syrup. So I'm sticking with the sugar.
Thanks to all for your input.
