To me, so far, it's 64oz. "Water Wells" for the win. $9 or so from
Tractor Supply. 7-lb size (the 10's impossible to put together!) "Harris Farms" feeder from
TSC also. I'm very new to chickens, the land owner's "throw the feed onto the dirty coop floor and put water in a dog dish" methods were not doing it for me. I needed something that works and I needed it immediately.
I am amazed how well these work!
For the feeders, I hang 'em from a string, and I made "lids" from the bottom half of a gallon milk jug for the tops, to keep poo and sparrows etc., out. Careful placement (what perches up, will poop down) will result in a SQUEAKY CLEAN feeder! The "Water Wells" are 1/2 gallon hamster bottle type waterers, built like little tanks and made in the US even.
I'm sure it's possible to build things that are better, but if you need something that works, STAT, I can sure recommend these.
