I'm starting a new flock of 25-30 birds with 2 or 3 roosters. In the coop planning stage and I've seen advice that you need "more" than the commonly quoted 4 sq ft per bird and 10 sq ft of run when you have multiple roos but I haven't seen any specific guidance. I realize these are just general guidelines but I've never had roosters before so I'm trying to get some practical advice on how big our coop needs to be to accommodate 24-26 hens and 2-3 roosters. They will all grow up together. They will probably have a 2500 square foot run-at least that is the plan for now. We are either going to convert a shed or carport for a coop of this size and I'm trying to narrow down my shopping list and keep my budget from ballooning. Thoughts?
