I am wondering if any one has links to good guidelines of how big to build a coop? We have a coop and run that was on our property when we bought the place, but it is in serious need of a redesign. We don't get much snow, so the chickens will be able to go out in their run during the winter. I picked up 8 chicks yesterday, 4 RIR, 2 Buff Orpingtons, and 2 Barred Rocks. We might be getting a couple of EE as well. The main things I need to know are: 1. How much sq footage per chicken 2. How many roosts? How long should they be? How far off the floor should they be, and how far apart? 3. How many nest boxes and what dimensions? 4. Is there anything I should consider about these breeds in the design of the coop? Thanks so much.
