I agree 100% with this statement from Beekissed, ".but I do insure my food animals have a good life as I can give them before they die."
But, I have a 7x4' coop, with the access door always open so the hens can come and go as they please in a 40x60' fenced area.. I have another coop 8' long but all 11 of my hens prefer to roost in the smaller coop together. Your limiting factor is your run size, if you can increase it you can increase your hens to more than the 3-4 that your run will currently support. I wouldn't suggest 11 hens in that size of coop, my crazy hens just don't seem to mind.
