How is that a chicken can lay "a blue egg"/?

Araucanas lay blue eggs, other chooks lay brown, beige or white eggs. A friend set some eggs that were laid by an araucana that had mated with a barnevelde rooster. Barneveldes lay brown eggs. The chickens that hatched lay green eggs and have passed this on to their offspring. The eggs come in greens from a lovely pale green to olive green.

The colour of the shell makes no difference to the flavour or appearance of the egg inside.

you can feed them dyes

This dependss on food and breed.

THEY DO?

The same way a robin can lay a blue egg. There are different breeds of chickens and one breed, the Auricana, lays bluish green eggs.

I own 16 chickens, but don't know. I googled it for you though.

That's no ordinary chicken.....that's the Easter Chicken...once a year these Easter chickens get together and help cousin Bunny.

Hope this helps.

Good luck and best wishes.

Because she can't lay a green one.
