So I am making the leap into a small egg production operation (eating and hatching). I want to have 4 coop and runs that are essentially 8ft wide x 36 ft long. The actual coop will be 8x8 The covered portion of the run will be 8x8 The uncovered portion of the run will be 8x16 3 coops will have one single breed and the 4th will have my mixed flock. I figured 24 birds in each coop/run. Breakdown is 22 hens and 2 roos. Is this correct or could I do more hens or roos?
