I'm so excited! I finally found a Chicken Coop that will hold all my babies. I wanted to make sure my run is large enough, and yes they will be in it the majority of the time. Even though my yard is fenced in, I need to keep my dogs away from them. I want to plan for 16 chicks...we have 11 we are keeping right now out of what we have (some are roos we are in the process of getting rid of), but we will most likely bump back up to 16 this summer. Is 160 square feet of run space an accurate number? Or do they need more or less?
