Our bucks don't come to feeders. We get them once a season. They just check does and lucky to get them on cam. But you should get some eventually.
Where I am (Deep East Texas), it is very unusual to see a 'mature' buck at a feeder.
Post rut and after the season....sometimes, but generally they just cruise around the perimeter, sticking to cover and looking for does.
We run feeders to keep the Does in the area. The Does are the 'bait' for bucks. Now... I do have mature bucks stop and feed on hand broadcast corn I've thrown out in secluded spots or shooting lanes, but you normally won't catch one under a feeder.
It's very different here than other places in the State (Hill Country, South Texas, parts of West Texas).
