Colors of my Chicken eggs?

[Chicken_girl33]

I have one Americauna and the rest are supposed to lay white and brown. They are all just starting to lay. But when I looked into the egg cartons today I saw some blue and some olive green eggs. How is this possible?

Someone is not who they are supposed to be! You have a mystery on your hands.

I know right!

Hi and welcome to BYC We're so happy you've decided to join us

Post some pictures of your girls, I'm sure someone can help you sort it out.

A lot of times chicks sold as Americaunas are really Easter Eggers. Share some pictures with us and maybe we can tell.

Thanks for joining us!

Could you add pictures and the breeds? We could help in possibly identifying who's laying what.

Welcome to Backyard Chickens! Easter Eggers or ameraucanas generally lay blue or green eggs but sometimes darker colors fade away as age increases. I've noticed that colors can vary when a pullet has just commenced egg production. Post in this forum if you have anymore questions like these. https://www.backyardchickens.com/forums/chicken-behaviors-and-egglaying.18/
Hope you enjoy it here as much as we all do!

Hi and welcome to BYC. These links may give you some insight as to what is happening in terms of egg shell colour. Sadly, the physical appearance of a bird will not help.
