I made this chicken feeder. It is made out of 1 piece of 3 inch pipe 2 end caps and one 90° elbow. I cut a 1.5 foot piece off one end and drilled 1.75 inch holes with a door knob style hole cutter. I fit them together and stuck it through the hole in the chicken wire resting it on the bottom. I attached it to the 2"x4" with a metal strap with a piece of 1"x3"x 4" spacer made of scrap wood. I put a handle on the top of the top end cap.for easy removal and easy filling. Chickens are already eating from it.
