Outside the coop
Inside the coop
This was a design from another BYC member and it really works great! We made it to hold 100lbs of feed(for winter) and there is zero waste. I had hubby make the tray removable, so I could clean the feed that turned into dust. It is slanted near the tray, so it falls down. It never flows out and I check it 1-2 times a month to see if it needs refilling. There is a shelf above preventing poop from falling in.
I love this feeder. It really is nice that it doesn't take up space inside the coop.
It was 100% free since we used scrap wood.
