I plan on cutting up 4 of them and them some whole. I did not add any salt to the ice and water mix when I butchered them. They were 6 months old. Maybe I waited too long.Is your plan to break them down or leave them whole? Five days is a very long time. Mine generally loosen up within 24-48 hours, but my turkeys can go 4-5 days. If you're planning on breaking them down, I'd try one and see how it goes. How old were your birds at processing?
