I have been feeding chickens duckweed fertilized with nightsoil (mine). What kind of symptoms or diseases could a chicken get from eating doodie? Has anyone tried fertilizing this stuff with chicken manure? I don't plan to do that because it seems riskier, but they might get their poop in it... and I'm curious. The chickens have available grass, chick starter, slightly spoiled kitchen scraps (potato salad, lasagna, hummus, etc), various weeds, and juniper soil. All of these foods they like but they will rather eat handfuls of duckweed most of the time. The only things they seem to like more are meat or maybe cut corn and brown/wild rice. They were eating so much of it I figured I had better not let them eat out of the little tub ponds so now I leave it in fresh water for a day before feeding it to them.
