Olive Egger chickens are a popular hybrid breed known for their unique green eggs. These birds are a result of crossbreeding any breed that lays blue eggs with any breed that lays brown eggs. As a result, their appearance, personality, and egg-laying capabilities can vary greatly. Despite this, Olive Eggers are generally considered to be good egg producers, with the ability to lay 3 to 5 eggs per week, or around 150 to 200 per year. In terms of appearance, Olive Eggers tend to have gray or black feathers and can live for up to 8 years. They are also relatively small, weighing in at 6 to 8 pounds on average. Olive Egger chicks are often born with darker feathers and can be sexed by the presence or absence of a white dot on their heads. As adults, Olive Eggers tend to have a calm and friendly personality, making them suitable for beginners. They do require a minimum coop size of 4 square feet per bird and can cost anywhere from $4 to $9 per chick. Overall, Olive Eggers is a unique and interesting addition to any backyard flock.
