I hunt near Brady where we feed year round. For Texas that's not too far.
Since I am there all of the time and can adjust the feeder times every few weeks. I set the feeder to about 15-20 minutes before sunrise year round.
The evenings this time of year when it is hot I throw about 30 minutes (or less) or so before sunset. Cooler weather an hour or so.
So now they are set at 6:45am and 7:45pm,(a few are still running at 8:00pm)
I set the feeders to throw a bag a week so I can keep up with refilling them at near empty easier. On some that is 3 seconds, other feeders 5 or 6 seconds. I'll speed that up a bit closer to season.
