I agree. My great grandmother was 104 and still living alone when she died. My grandmother was 98 and my mother is 94 now and still living on her own and going strong. All good old American farm girls. I moved to the city, got a really good job, worked hard, had two heart attacks, high blood pressure, diabetes...retired, bought this farm, got some chickens, geese and ducks...blood pressure is almost normal, diabetes is under control with diet. A lot can be said for a good, quiet and simple life.I completely agree with what lazygardener said here. The way I say it is that all chicken plans are subject to change. What you think will work for you may not and what you think isn't going to may be your best bet in the end. Chicken breeds come to mind. You pick a breed that most say will brood chicks, then that particular line/strain just doesn't. Hatchery stock is famous for not being or doing what it is supposed to.
And to that last statement in the quote, definitely once you get going, steer clear of "free flea market chickens" and the like, to avoid wiping out all your plans due to some nasty carrier disease. Best of luck.
I remember my grandparents' farm in west Georgia and how they'd go pull a chicken to butcher for dinner. They didn't have Cornish X but all sorts of skinny whatevers and sometimes, it would take a couple of them. I was there for hog butchering and calf castrating and all other farm activities. It's a tough life but a rewarding one. My grandfather lived to be 100 years old and my dad is going on 94 himself, though he left the farm when he had to make a living for his daughters and moved to the city. I think farm people just live better, even if they don't live longer. JMO.
