Question: how many sq ft do chickens need?
Answer: So for 4 chickens that free range, you only need a coop/run area that measures about: 4 by 4 feet (16 square ft). But it is always best to give them as much space as you can. For chickens that will be inside the run all the time (never free ranging), you need to bump that number up to 10 square feet per bird.
