I have been hoping for more info and posting on California Whites. I have my first pair at about 16 weeks now. They are soooo flighty and independent! Both of them, “Big” and “Little” (who are getting harder and harder to tell apart). Fine by me so far so long as they visit more in the wild grass patch and less in the raised beds…
If I understand correctly, this breed was created to fill the need for a commercial quality white layer that was less flighty and better suited to pastured egg production than the commercial strain Lehorns.
They don't seem to be very popular with backyard chicken keepers, but I find them fun.
