17 Gallon Custom Made Chicken Feeder. It will feed 10 chickens for one month with ease, chickens will stick their head in there and feed without dragging the feed out and wasting it. The lid is lockable and even if they get on it you just clean the poop off before refilling, lock it in place and you are good to go. I used to refill my 5gal normal chicken feeder every 3 to 4 days and the mess the chickens would make with grain and poop all over the place was incredible. Problem solved! Even have a couple of dirty ducks feed in it without spilling the feed all over. Just fill it up and watch the feed twirl down while your flock eats. Use meal worms to train your flock.
