ok - here's chicken math for you wife... out of 20 eggs, with luck maybe 18 will hatch. Then, expect a 50/50 male/female ratio. So now you've got a maximum of 9 that you might be keeping. However, you'll have better luck rehoming roosters in pairs, so any excess hens can easily go on CL along with a boyfriend! See - you're down to a normal amount in no time!
