I'm trying to learn chicken math and I came up with this. If I lose a chic/chicken that would be worth 5 morechick/chickens. Is that close enough? My wife doesn't agree. She says we have enough. 3 roosters and 12 hens. We lost 2 chicks right from the start about 4 months ago,and lost 1 rooster last week due to the heat. according to my figuring, we need 15 more chickens. Our coop is big enough for 30 but she says no! She tells me that when they are established layers, that we should get acout 3 doz. eggs a week, that is if each one lays 3 eggs a week x 12 hens = 36 eggs. I tell her that won't be enough. How do I change her mind?
