don't put rice bran in the feeder as it will gum it up pretty good. unless you sprinkle it in there with the corn, but even then it can gum things up and you end up with a nonfunctional feeder that needs cleaned out.
I recommend placing rice bran on the ground in piles. If you are going to use it, that's the way to use it.
You can also use corn and roasted soy beans, that is a great food deer love in my experience and once they are on it they have been reported to bypass other feeders to hit that one.
bottom line with attractants, they will draw deer in if there are not many other feeders around they are patterned to, but they aren't going to steal many deer away from other feeders. The deer will have a pattern of going from one feeder to the next, so don't get too crazy in the amount you spend on attractants.
