10 total chickens. 8 pullets, 1 hen, 1 probable roo. I read that nesting boxes should be 4 to 1. 9 girls - 2 nesting boxes is too few, so need 3. 3 nest boxes is good for 12 chickens. Only one is laying, so I need 11 more chickens - right? No, wait....that makes 21 chickens - what if my "roo" turns out to be a hen? So I need 6 nest boxes because 5 is too few for 21, but then I need 24 so that my ratio is 4 to 1, so I need 3 more. But only the one is laying now, so, darn it! I need to go get 23 more chickens pronto!! That's my story and I'm sticking to it?
