Howdy, we processed our first six barred rock roosters 2 weeks ago, at 13 weeks of age. They were small, but grandma fried them up and they were FANTASTIC... best fried chicken I've had since I was a kid. There was just one problem - The wife and I spent hours getting out black pinfeathers. I was wondering if there were so many because the roos were still so young, at 13 weeks? I'm waiting until 18-20 weeks to process the rest of them, so they get some more growth. Will they have fewer pinfeathers at 18-20 weeks?
