This is why I like reading all the threads, this is info I did not know. I haven't had an issue with processing older birds yet since mine have always been fairly young, If I do process an older bird can they go straight to the crockpot from processing or should I let them rest a few days?
That's not an easy question. Sometimes rigor mortis sets in really fast and sometimes it's delayed. I haven't figured out why yet.
So, if you're fast and lucky enough that bird can go straight to the pot.
When I was a kid, my dad used to butcher and on rare occasions cut slices of meat (lamb usually) that my mum would cook immediately, that meat was always fine. But most always the innards would get eaten on the day and the carcass would be left to rest.
