The two traded land they already owned and cash for the acreage on the St. Charles Mesa in August 1914. There they built their original milk barn where they continued to deliver milk and eggs into town. The original milk barn burned down in 1935 and a smaller milk and horse barn was built in 1936 to replace it. Anton Koch, another Swiss immigrant, came to work on the dairy farm in the early 1920’s and married John Wyss’s daughter, Anna in 1925.

Anton and Anna’s son, John, later took on the farm operation in 1961 when his father passed away. At this time the dairy herd numbered around 40 and the farm also had a few beef cows, rabbits, pigs, and chickens. John married Kay Rose in 1958 and the two had three children, Mark, Barbara, and Paul. Mark took over the farm operation after his father. Today the farm now grows alfalfa for hay.
