Uh-huh?
They'se gonna end up with a whole lot of old chickens and absolutely no eggs that way.
And if they do? Some of us actually do keep chickens because we like them not because they produce eggs. My 4 roosters, 10 hens and 6 ducks see my avian vet when they have a health issue. (Avian vets, BTW, are more expensive than "regular" vets, because avian medicine is a specialized field of veterinary medicine.) In 2014 alone, I spent around $5,000 on vet care for various of my fowl. I could have bought a whole lot of eggs for that money.
