Blue Andalusian

Historical Origin

Spain (Andalusia) · Mediterranean

The Blue Andalusian is a striking Spanish breed with slate-blue plumage laced in darker blue — a color that follows an interesting genetic pattern where two blue birds produce blue, black, and splash offspring in equal proportions. An active, heat-loving layer of large white eggs, they are popular with breeders who enjoy the genetics challenge. Best in warm climates with free range.
