So we started out with 4 adult chickens and 5 chicks. So we built a coop big enough for 10 chickens. Then decided we would like to produce about a dozen eggs a day...we have 7 hens...I think we need more!! So now in order to house 1 roo and 14 hens...we need to go bigger. So here is the construction process of our new 10X10 walk in coop!!
