I have 5 pullets (assuming none of them are cockerels) who are gonna be ready to move outside in a few weeks. Our previous house owners built this setup for their dog. It's a boxed off area inside a shed with a dog house leading out into a dog pen. It still needs a lot of work to get it ready for the chickens but from the pictures below, does it seem like a suitible sized coop and run? The run is about 9x9 and the coop measurements are on the picture. We plan to add at least 2 long windows covered with hardware cloth for added ventilation.
