Her feathers are blue/gray colored and her eggs are green! What's not to love about a Blue Olive Egger? This beautiful hybrid chicken is a wonderful layer of x-large green eggs (approx 290 eggs/year) and they will be a cool addition to your egg carton. Blue Olive Eggers are known to be docile and active with occasional broodiness. Most have a sweet, tiny crest of feathers atop their heads, paying tribute to their Cream Legbar progenitors. Approximately 5% of these fabulous hybrids will lay brown eggs.
