Well....we hear this question all the time.
First and foremost you have to define what your real objectives are.
1) Is you feeder a spin feeder or free choice(gravity)?
2) Are you feeding to attract and kill or do you want to implement a year around supplemental feeding program for overall herd health.
Feeding deer for herd health vs. quickly attracting deer to hunt and kill are entirely 2 different objectives. Both can be accomplished with great results.
