I threw this together on Sketchup. This will be mine and my wife's first time raising chickens. We are looking to get about 3 hens and then maybe a rooster one day. The floor is 4' X 4' and 26" from floor to ridge. It will be elevated 15" off the ground. The nest boxes are 10" wide by 8" tall by 10" deep. The run area is approximately 10' with access under the platform for shade. Is this big enough for 3 hens and a rooster? Are the nest boxes big enough? Thanks for the feedback.
