Going through my first attempt at butchering today. Don't have an automatic plucker. Have to do it the old fashioned way. Do chickens have smarts? Can you kill a chicken in front of the rest and still have them like you? Do they freak out from the site or smell of blood? I used to raise and kill rats and the rats go nuts if they smelled blood from a comrade. After they are plucked and cleaned, do they have to rest in ice water before sealing and freezing? Would salt water be preferable?
