I've hunted multiple areas with feeders for hogs and they come when they want to come, day or night. They are smart and learn quickly about pressure, but won't "go nocturnal" all the time. If they're hungry they're going to eat.

Dawn and dusk are good times. If you have a red dot scope/optic on your gun, all the better.

Nighttime is good, and get a sensor-feeder light. Moultrie makes some. Others can be found on https://elusivewildlife.com/shop/hunting-lights/feeder-lights.html and also https://texasboars.com/
