Baiting deer is legal in Texas and I've hunted over a feeder some. What I've seen though, is that you can sit there and watch does and small bucks lining up in the brush, waiting for the timer to kick on, and they charge the feeder when the corn starts hitting the ground. Even if you wanted a doe or small buck, it's kinda hard to get a clear shot on one deer out of that mob. Always a deer blocking the one you want, or in position to get wounded on a passthrough. The big boys won't come in to the feeder. So, my tactic is to set up an ambush on a trail about 50-75 yards away from the feeder.

No different than hunting a trail to a planted food plot.
