California White hybrids strongly resemble the White Leghorns they were developed from but are slightly larger and have a few black spots on their white feathers. They are laying dynamos, producing about 300 large white eggs a year. California Whites are active birds and one of the best white egg layers for backyard flocks. Adding a few California Whites to a flock of brown egg layers adds color diversity to the egg carton. Like White Leghorns, the chicks have yellow down but have black spots on their heads and feather tips.
