Anne and I have been working all summer remodeling our barn because I want to breed my own line of bbs Orpingtons that will be an especially dark blue by crossing some other selected lines with mine (see my BYC page). What we have in the barn are: Four 4- X 10- foot coops (40 sqare feet) Two 4- X 4-foot coops each with an additional area of 2-foot X 8-foot area (32 square feet) or these two can be combined into one coop with 64 square feet. Two 2- X 16-foot shelf coops (each 32 sqare feet) These can be two brooders or four 2- X 8-foot brooders. I will only be able to let each coop free range once a week, and there is no run, i.e., they will be in their coop 24/6. Question: I have seven various roosters from which I will choose four for breeding. Considering that there is no outside run for any of these indoor coops, what's the maximum number of hens you would suggest per rooster for the least stress of the hens and the rooster in these confined coops that they will leave one or two days per week in turn to free range? BTW, you've probably surmised that I feel guilty confining chickens like I'm doing now and will do more later. Also, this breeding program will take more than a year for me to get a rooster and six or eight hens the color that I want.
