Holy SMOKES that's a lot of birds. And you'll keep ALL the hens as layers?... already hatched @300 chicks ........ hatching out about 200 more before stopping for the season.

I'm not sure that's a setup that many of us would find "easy"
BUT.. I'm actually genuinely curious to see what the numbers say for you because I also like to see how things stack up in "actual" results vs "theoretical probabilities".
