Guess the answer depends on your climate and how you plan to do the daily feed/water routine and how you manage your flock. It varies by climate, how large the flock is, whether they are in coop/run confinement or free range.Some people here don't keep food in the coop, with the reasoning that it is messy and when it gets wet, smells up the coop and draws flies.
Some don't have water in their coop as it gets spilled and doesn't drain.
Some keep both food and water in the coop.
I'm just trying to figure out the layout of my coop and what is the best way for the birds.
I was just going to have food in the run, not the coop, but have water in both run and coop.
