RE: HELP WITH ETHICS
I would consider it baiting since you are hunting with the knowledge of the feeder, and thus relying on it. Whether that is legally baiting, well that's up to the regulations of your state.
However, you might want to check your states wildlife regulations, to determine if such a feeder is not illegal. Habituating wild animals to humans is generally frowned upon, and often feeding is an illegal practice. Your neighbours may be breaking the law,
