I wasnt sure if you were being sarcastic or not lol... if we don't lose a single one (and were not holding our breath, historically weve always lost a few, dogs, predators, etc) we will have 20 in total.
Most of what we ordered are smaller in size (not huge hens are full maturity) the house is 5x6 but we intend to build an additional house should it prove to be too small. The 5 nest boxes was how it was planned out, we hadnt designed it at all. Were excited to watch them grow and see how it works. Loving doing this build, its been fun so far!
I apologize if my post came out wrong. You can't have too many nest boxes. Even though it seems a lot of people have the same complaint I do of their chickens using exclusively one or two for Brody hens and things like that. And if you're getting up to 20 and five is a good number. What did they say the golden rule on that is one box per every 3 I think.
Either way it's looking great !
