Are you buying broilers or old layers/roosters?
If it's old birds, and I'm talking even a year old (layers or roosters), that's what you get.
You can't even cook the rubber out of them in a pressure cooker.
If a brother butchers yard birds at around 7 months, they're good for soup, and that's about it.
If you're going to buy birds for the oven, you want broilers. They're usually available in the early summer, mostly from kid's 4-H projects.
