Hi, our family has a medium size suburban yard with lots of grass and places for our chickens to scatch. We have 5 chickens that we allow during the day to run around our yard as long as someone is outside, which we always are. Our coop has a slanted roof to let water run off. The coop(without the roof)is 70 in. in length, 40 in. in width, and 40 in. in height. We have, inside, a small nest, food and waterers, and perches for roosting. We also have a run which measures 70 in. in length, 100 in. in width, and 40 in. in height. We want to know, how many, if any, more chickens we can put in this coop. Thank you in advance for your answers.
