I'm going to be building a coop for a dozen chickens. This will be my first time having chickens so as you can imagine I have tons of questions! First, how much room in the coop is recommended for each bird? How many laying boxes do I need? How big should the run be? Dirt floor or wood floor for the coop? How tall should it be? I'm on a pretty low budget so I'm not looking to build anything extravagant but I want it to be a good coop for 12 chickens. Your oppinions or answers will be much appreciated,I am also interested in good brooder designs. Thanks
