The Olive Egger is not a pure bred chicken breed and can be made from several crosses. Generally it is made from crossing a real dark brown egg shell layer with a real true blue egg shell layer. This will produce in the first generation some great olive colored eggs for your table. Our breeding is from pure Cream Legbar Rooster over our pure Welsummer to create a F1 Olive Egger. Good layers of various colored eggs. First eggs maybe small but will get to medium to large size. You will love these Olive Egger chickens.
