The company was founded in 1918 when Walter Ingham Sr. purchased of bush land in Casula as a gift to 18-year-old son, Walter Ingham. Walter Jr. embarked on a fruit and vegetable farming venture, eventually moving into the poultry business. Starting with just one cockerel and six hens, his flock quickly grew to 1,000 birds. On his death in 1953, his two sons, Jack and Bob Ingham took over the small breeding operation and built it into the largest producer of chickens and turkeys in Australia.
