I have 10 hens. 2 each of Buff Orpingtons, Australorps, Partridge Plymouth Rocks, SLW, and Partridge Cochins. I can have 25 hens, and 1 roo in my area, but for the area we planned the coop, we felt 10 was plenty, and we didn't want a roo. Also, at the time I had no clue so many people would want the extra eggs. I have more requests for eggs, than I have eggs to go around. Still, the 10 are plenty right now. I would want to make my inclosed run much bigger if I got more. The hen house is big enough for more though, but this gives them all room to move around.
