My best tip would be to keep the chicken food in the coop. That's really the worst problem I've had with chickens. I used to keep the food out in the run, they would spill it, and it would collect on the ground, get wet and stinky! HORRIBLE!
So now chicken feed is kept inside the coop, and I have the feeders sitting up on crates so they are at beak level. There is hardly any waste this way because they can't get their feet in there and scratch it all out.
This saves me alot of work, and also saves me money!
