That's a pretty substantial backyard operation.
At least where I live, you can't have chickens in quite the same way our great-grandparents had. You need to comply with veterinary regulation for one, and for good reasons.
They would probably need more pasture in monoculture hellholes that have cornfields for 100km in each direction.
12 weeks is incorrect, you can buy the same Cornish crosses that the big farms use. So they can be ready in as little as 6-7 weeks but I usually stretch it to 8 or 9; my time to process them is fixed so I might as well get a little bit more meat for my efforts.
I use a chicken tractor that is big enough to let me hold about 33 at a time.
So it’s an operation that needs to run for about half the year. If you time it right, you can work around vacations and stuff. Daily operations are actually pretty minimal in terms of time spent, but you do lose three weekends a year to process them if you don’t outsource that.
All of that to say: I’m not sure if I want to agree with your characterization. It’s less of a time commitment than you think. But there is a substantial cost to it all: capital costs are notable and the cost of feed and birds is such that you basically break even against high-end organic products for sale. You’re always going to look at the Costco chicken and wonder why you are doing it. I treat it as a “touch grass” hobby that kinda breaks even.
No real point, just excited to have something to say about this haha
