We have 2 feed stations on a property that I hunt and I don't believe there is any evidence that it makes them nocturnal or doesn't draw bucks. We have 1000s of pics and I would say it's pretty much an even split on night versus daytime pics. I would say it's also close to 50/50 on bucks and does at the feeder. Some of the best bucks we had came consistently during the day. it's not some magic potion but I do think it has a place. I think hunting pressure has way more to do with them being more nocturnal than anything. Also when we had that long warm spell in gun season almost all of our pics were at night but as soon as it cooled back off they were back on the feeders during the daytime. We had pics at all times of the day too but we do not pressure this place and it's mostly just bow hunted.
