To fast forward I don’t have chickens yet but my first coop is almost done. It’s a 4x4 coop with an attached run. Skipping pass the brooder stage I’m planning on building a pvc auto feed and waterer but I’m unsure where to mount them? Main question being.. 1. Where to mount the automatic feeder and waterer? (Inside or out). 2. Should they have constant access to the feed or only when I allow? 3. How much feed should 4 teenage or adult hens be feed on a daily bases? Also would only 2 nest boxes work for 4 hens? I heard they like to share. Thanks for any answers.
