feeders work good,but with keeping it in the same spot, eventally with time every animal in the area will be using it,just set the timer for only a few seconds, so your feed will last longer,corn is probably the most liked by deer,but its a carb, no protein.use soybeans great protein,(big horns),i usually mix mine ,corn/soybeans,and its alot cheaper than the deer feed,and i usually set mine to feed in the middle of the day and middle of the night,normally most feeding times are early morning and evening,good luckand hope the squirrels don't chew a hole in the top of your feeder,one on one
