So, it turns out that there really is such a thing as a blue chicken. Yep. Blue chicken. It's actually a bluish grey. Some of the darker ones are kind of a gunmetal blue, then you get the 'splash' variant which is a lovely soft blue-grey with lace markings. They're called Blue Australorps. I got one this week. A blue chicken. I wish I could remember how to post photos here.

Huh. Who would've guessed?

I'm going to see if this link works. Not one of mine, but a photo of a young Blue Australorp pullet from the backyardchickens forum. https://www.backyardchickens.com/hredirect2.php?c=5726451

The link works. The chicken's coloration is like a Russian Blue cat's. Kinda cool.

Seems more gray than blue, but more lighting might show more of the blue tone.

It's a pretty chicken!
