With tough ol chickens. I had to cull a year old rooster the other day, so I put him in a stock pot and simmered him for about three hours. Then I refridgerated him, still in the stock, and when I went to cut him up the next day I tried a piece of the breast meat and it was like chewing toothpicks! I spit it out it was so bad. Can year old chickens be made edible? I have several more I need to cull so I'm wondering if I should even both cleaning them, or just compost them.
