I love the look of this idea. I have heard that you can use rabbit cage waterers for chickens and just haven't tried it yet although I am always frustrated by what a mess my chickens make out of any kind of chicken waterer that I put on the ground. As for the scratching, I am wondering what kind of feed you were using? If you used pellets and it got scratched out then presumably the chickens would eat it and it wouldn't be lost. But maybe that is just too much for them to eat and they don't stop until it is all gone. In which case wouldn't you have the same problem with the PVC feeder? I am just trying to figure this out. I only have 8 hens now, down from 15 so I am not a big operation, just eggs for family use and some to donate. Still, anything that makes life easier and my chicken coop neater is a good idea to me. Since chickens do love to scratch, maybe giving them some things to scratch for would satisfy that urge and they would leave the food in the pipes? Or maybe smaller pipes so they couldn't get their feet inside so easily? Great idea, maybe some modification would help. Any comments appreciated.
