Marans chickens are excellent layers of brown eggs while Ameraucana chickens are famous for their blue eggs.

So, despite the eggs being laid by a blu egg layer, the resulting offspring will lay olive eggs because there is a mixture of blue egg genes and brown egg genes.

Olive egger chickens carry the combined features of their parents. These birds are not large but are medium in size though some may be large or small depending on the dominant genes.

On average, olive egger hens weigh 6 pounds while roosters weigh 7-8 pounds. Those that carry more marans genes will be larger than those with more Ameraucana genes.

Raising olive egger chicks

Raising baby chicks can be fun and interesting. They do not require much but without the right knowledge, it can be hard for you to raise them successfully into adult hens.

So, what do they require? Let’s roll!


Just like us, olive egger chicks require a well-balanced diet. These baby chickens require feeds that are rich in protein but not as much as turkey poults and game birds require.

Buy quality chick starter feeds from well-known manufactures or a reputable store near you. This feed should have 22-24% protein content in it.

Remember that the young birds are in their rapid growth stage and need to develop muscles and feathers as quickly as possible.

Put chicken feeds in clean chicken feeders and make sure there are plenty feeding stations so that the juvenile have equal feeding opportunities.

Chicks also need plenty of clean drinking water. Multiple waterers will make sure there is plenty of it at all times.

When it is very cold and temperatures drop to freezing point, heated chicken waterers will make sure the water does not solidify. They also keep the water some degrees warmer.


Young chicks do not regulate their own body temperatures. These baby chooks require supplemental with heat.

They will remain in the chicken brooder where they will get extra warmth until they are about 6-8 weeks old and fully feathered.

Provide enough warmth because cold chicks can chill to death. When cold, they become fuzzy and huddle together under or near the heat source or in corners.

Although warmth is vital, too much heat can bake the tiny chooks to death. When hot more than they can handle, they drink a lot and stay far away from the heat source. They also get noisy, uncomfortable and try to jump over the brooder wall.


Shelter is one of the basic requirements for your olive egger chickens. Chicken runs and coops will provide security from predators and also keep them away from elements.

When it is cold heated chicken coops are a primary source for your chicken’s heat. Inside the coops they will find a good place to lay their olive green eggs and hatch their chicks.

Ensure your chicken coop has enough roost bars because unlike ducks that spend the night on litter and chicken bedding chickens roost.


After the brooding period, your teenage olive eggers are fully feathered and can now be moved from the chick brooder to the coop.

It is likely they might get bullied by other chickens or be an easy target for predators when out ranging. If you have breeds that rank top on the pecking order like Lavender Orpington chickens, it is good you have a separation pen.

Olive eggers are not assertive and are likely to face harassment. This will deny them peace, equal drinking and feeding opportunities.

Take them to the chicken coop at night and place them on the roost bars. In the morning, the dawn will find them together with the others. This way it will be easy for them to adapt and get their place unnoticed.


Olive egger chickens are good for the colored eggs. They also make a good table bird for a small family. Having them adds colored eggs to those white brown and white eggs you are used to.

Keeping these birds will help you utilize those chicken scraps like left over raisins and extra cheese that would have gone into waste.
