I have parted out birds because they take less room. I managed to fit 2 Jakes cut up into a full refrigerator yesterday.We've raised nine CornishX Rock Cross to five weeks. Tomorrow the first three go to our Mennonite lady to be processed. (I can only fit three at a time in the fridge.) They look to be nearly as big as some of our adult layers. I'll come back tomorrow and post their dressed weights. They're a little frightening, actually ...
I also have a dedicated cooler I swap jugs of ice out every 8 hours. I can fit 6 chickens and 2 jugs of ice.
