I minored in math and my bachelors was in computer science. I was a rocket scientist before I became an author. I have no excuse for this. We agreed on 6 chickens. We bought 2 Leghorns, 2 Black Sex Links and 2 Golden Sex Links. I bought 4 EE from a breeder. I wanted turkeys and geese, so 2 turkeys and 2 geese. They had EEs, so I bought 2 of those and 2 RIR. Saw cornish X's on sale 2 for 1 -- bought 6. With the Cornish X they offered me two RIR roos that looked like pullets as a 2 for 1. Got 2. Didn't realize the BSL were actually BR and thought they were roos. Bought 3 BSL pullets to replace them. Lost 1 Cornish x; butchered the other 5. Lost a turkey; DH says buy 4 Buff Orpingtons. So: 6 = 2 + 2 +2 + 4 +2 + 2 + 6 + 2 - 6 + 3 + 4 = 23 chickens plus 1 turkey and 2 geese. Chicken math is catching. My DH has it too. Maybe it's a decimal point thing.
