The wife and I are trying meat birds out for the first time. We have a very small flock of 11 cornish cross broilers. Is there a specific way to chill these birds after slaughter? I've heard bits and pieces, but nothing really concrete. Is it just regular water and ice for 48 hours or more? Or do you put sea salt in the water, or something else? If so, what for? Any tips will help. They're currently at 4 and a half weeks.
