I've been using a plastic hanging feeder to feed my 2 bantam chickens which worked great for 2 months. however the powerful australian sun has cooked the plastic on the hanging feeder so much that it's become brittle and started to crack and crumble. also the plastic hanging water also lost some of it's red colour which means that it's seeping into the water. since I'm trying to raise my chickens organically I'm not real thrilled about them ingesting plastic and dyes. so what other options are available for feeding and watering that don't involve plastic?
