big mature buck will avoid a feeder during daylight hours 95% of the time,especially if there is natural food for them to eat, unless its during the rut thats when he will make a mistake.
I agree with this.
My problems are that I have NEVER seen a deer come running to a feeder. That might be our herd, but that is the reality here. I have seen deer slip in right at dark to see if corn was there, but never coming immediately after the feeder spins. (I will say that last year we had a doe that would come to a trough immediately after we had left, but again, this wasn't at a spin feeder).
Also, hogs will find your feeder and clean up any corn on the ground and may turn the feeder over to get to the corn.
We have lots of racoons, squirrels, crows and oppossums that love to eat the corn as well.
