Coons will destroy most spin feeders. They will send one to the spinner and he can empty a feeder in one night. I ended up installing cages around the spinner. I also switched to alfalfa hay as our main feed 4 years ago. Coons don't eat it but deer love it. I supplement this with mineral and 20% protein blocks. Experiment with different feed and find what works. Try sweet feed when it's cold. You have alot of options in Indiana.
