So I will be butchering my chickens tomorrow for the first time. They are about 13 weeks old, Freedom Rangers. How long do you think it will take me to do. I will scald them but no automatic plucker. What is the reasoning for withholding feed? I will be doing it by myself, as my "helper" has backed out at the last minute. Do you all freeze them in vacuum sealed packaging or something else? Thanks for the advice!
