I have a 5 gal bucket with holes in the sides set into an oil pan. This is what I've been using as my feeder. My chicks are a good three months old, and the edge of the oil pan is about 6 inches off the coop floor. I just filled their bucket up yesterday with about 20 lbs of food, and it's already almost all gone (I have 20 chickens out there) QUITE A BIT is all over the floor. What the heck can I do to get them to stop wasting it all???? Feed is expensive!!!!!!!!! Thanks!!
