Hello Back Yard Chickens, I have 20 Chickens and in April I'm hopefully getting 12 chicks and that is 32 chickens if I have done my math right. And I do not do free range I want a coop connected to a SAFE COOP RUN and I was wandering 2 things... 1. How much coop + run space would they need? 2. What are some of your coop ideas? P.S. I have already looked through Back Yard Chicken Coops. And oh my budget is $400. Thank You!
