That is really interesting to me. We always butchered much earlier than that. Basically when the weather got cold enough. I remember us butchering hogs in November most years. This was the late 60s early 70s. Our butcher house definitely did not have refrigeration. Therefore, you had the butcher. when it was cold 'enough. We butchered hogs in the fall, and steers in the spring time. We too used a 22 rim fire to put them down.every New Year's Day, we butchered two to four of them
