A poop-free chicken waterer for just a few bucks using a bucket and a cent water dripping nipple. The website doesn't link directions but redirects to a sales website; it still has some good ideas, stuff that you could easily do at home.
Chicken water and feeder buckets DIY. For the water bucket used the holes in the top method. For the feeder, I bolted a large pot plant saucer to the bottom of the bucket so I could suspend it from the coop roof to keep rats and mice out of the feed.
