Help with breed is please?

[Matejka]

July 15th I went to TSC for feed. I left with 12 babies.
3 rir
6 blue andulusians
3 astralorp
I have previously had astralorps (black) and chicks were black. These were blue. Whatever, I figured chicks got mixed and they would be blue andulusian. I don't stress breeds, I like em. Now, 7ish weeks later, 3 ARE different. Their blue but have a noticeably darker head and neck feathers. Are there blue astralorps? What have I got?

Hatcheries do sell blue Australorps now, and TSC gets their birds from hatcheries. So that is a good bet. Photos will help, and also skin color, which can be determined by looking under the feet. White or pink in that area = white skin. Yellow in that area = yellow skin. Australorps should have white skin, and Andalusians, too.

They look right for Australorps. Those are good layers!

Yes, Blue Australorps exist. I absolutely love mine. The ladies are good layers and good flock citizens.
