Last year I bought 12 day-old pullets, and got 17 due to extras. I ended up with 7 due to naughty dogs. I got a cochin cockeral and pullet this winter. = 9 + 14 babies hatched this spring + 8 babies hatched under my Broody + 4 babies hatched last week = 35 chickens and chicks! In one year. And I am filling the bator as we speak... And to think, when I started, all I wanted was 12!!
