I don't know if they will be able to climb to the spinner on the feeder, but afterone gnawed through a rope and brought down my feeder, they snapped off the legs and spinner. This was a game country 55 gallon feeder. Be sure that your legs are thicker. Or use a cable and pulley on a branch thatis about 20' or higher off the ground, and use the winch on your ATV to pull it up. You should then wrap razor wire around the tree base to keep them from going up after it.
