My Chicken Babies

[DuckHen89]

Hello, I'm new to this forum, but it has been very helpful with chicken behaviors, so maybe someone here can help identify our chickens?

Background: my MIL Has a Black Buff Orpington, a Plymouth Rick chicken and recently(or several months ago) got 5 new babies. She does not remember what the name of the breed was so maybe someone could help? She was told their eggs would be blue or green...

Close up, clearer pictures are needed.

If she lays blue or green eggs then she must be an Easter egger.

This was taken when they were younger. As babies, they had yellow under bellies now they're black and grey. Though some do have small streaks of orange/yellow on their chest

they're easter eggers or olive eggers.
