No breed of chicken in the USA recognized by either the ABA or APA uses the term lavender as the variety recognition. Self Blue is the designation given to birds that carry the lavender gene. The self blue color is not new. Please use the correct terms when describing your birds and selling eggs. The description of the plumage colors does not use the term lavender either. Described as a light slatey blue. No red, yellow, orange or positive white allowed anywhere. There are some wonderful examples of self blue birds out there.
