I made a DIY Double pipe feeder last season. it was great for taking Game camera pics. But this one spike decided that he would camp out all night long and eat all the corn out of both sides. I had one Doe that waited for me to come out to add more corn. She figured me out in about 3 days. She watched me from a distance one day. She got familiar with the bucket i used and the sound of the corn jostling around. A couple of days later as i went out to add more corn she came around the corner from behind the shed. She was about 8 FEET from me. she had two yearling with her in tow. She came straight at me. I screamed like a 8 year old girl and dropped the bucket and ran back in the house. 
She was one of the ones tagged by the state and was moved. She had attacked a neighbors dog while being walked on a leash. I took the Feeder out a couple day later. It was costing me a lot of money. I have to buy the corn in 25 pound bags and don't have any other cheaper deal on corn. I might make this bucket feeder. looks like the feed would last longer.
