I sure was happy to find this thread. I have some Barred Rock hens that are about 18 months old and my other half is looking forward to having them fill the freezer. But I must say that the roosters we butchered, as well as the egg-eating hen who also pecked everyone else's feet, were just plain tough. The roosters were about 6 months old. I will admit that I am pretty new to this part of raising chickens and tough chicken is not one of my favorite dishes. Suggestions and advice are welcome!
Invest in a pressure canner and learn to preserve your meats by canning them. Canning makes any meat tender, frees up your freezer space and enables you to can up chicken stock as well. Makes for quick, nutritious, flavorful meals...with tender meat no matter the age of the chicken.
