I load my feeders with only half of their capacity and I attach weights to their underneaths in an attempt to prevent as much seed from getting to the ground as possible. When any animal eats seed from the ground beneath a feeder they are eating seed often contacted with bird feces, = salmonella and other nasties, especially in rainy weather. I also try to move the feeders at least several feet, once a week.

Yes, I know... but, it can't hurt.
