Right there with ya! Much better to know what went into that food when you raise it yourself. Our goal is to be self-sufficient. Not quite there yet with the chicken meat, since we eat more chicken than anything, but we're working on it.I understand that. I am talking about the supermarket mess that is injected with saline to make it appear plumper. Not to mention it has been fed arsenic to keep it from dying after being force fed. to make its breast larger. Rubbing down the meat or using herbs and spices, or cooking it with lemon in the cavity isn't bad. I just prefer to have my own eggs and my own meat that I know what went into it. Once finances stabilize, I plan on high fencing the side hard and either putting boar goats or hairless sheep, so I can butcher them and know where my other meat comes from. I try to hunt every year, so I know where my deer meat comes from. I have no love for the industrial method of ranching/farming. The USDA lets the big boys get away with putting garbage in the system you wouldn't catch them eating, not to mention all the meat recalls. I want to know where my meat comes from, and I am guess you and most of us do too.
That is why I mentioned the saline injected supermarket meat. Your method of tenderizing yard bird makes sense. I may just try it.
I usually wait at least 24 hours after butchering before I do anything with a bird whether it's freezing it or brining for roasting, to let the muscles go into and out of rigor mortis. I love to brine and get the different flavor combos into the meat. And then when I cook the roasted carcass remains to make chicken stock, the stock has even more flavor to it.
