History & Origins
Welsummers developed in Welsum, Netherlands, during the 1920s from local landrace crossed with Rhode Island Reds, Leghorns and others. Egg pigment and foraging ability were selection priorities. British backyard demand rose for 'Cornelius' carton aesthetics. Roosters appear on Kellogg's Corn Flakes packaging — arguably the world's most famous chicken illustration.
