Help Wanted: Chicken Breed Identification Specialist

[libertysmith]

After perusing these chicken forums, it seems I am facing a common predicament us chicken lovers find ourselves in.

I went to my local Rural King and listed off the chicks I wanted and waited for the kind man to box up my chicks, blissfully unaware that I would not be receiving my requested breeds.

2 of these chicks were supposed to be Black Australorps. Bird info below:

Cali
My estimated hatch date for her is 9/29 - she was much older than the rest of the girls we got.
Today, aged roughly 7 weeks, she weighed in at 1 pound 3.8 ounces.
She is all black with small spots of white on her wings (only visible when outstretched). She is starting to get iridescent (blues/purples, have not seen green) - only in direct light.
She has a few copper flecks on her neck (I don't have a photo of this).
Grey/black legs with pinkish/white bottoms of feet.
She does have leg/foot feathering but it's only one feather on each leg and one feather on each outer toe.

Baby Girl
Estimated hatch date is 10/10.
Today she weighed in at 1 pound 8.5 ounces -- aged 6 weeks.
She is all black with heavy iridescence (purples, blues and greens) - direct and indirect light.
Black legs with pinkish/white bottoms of feet.
Heavier leg/foot feathering than Cali -- thick line of feathers going all the way down leg and outer toes on both sides.
Obviously she is much heavier than Cali even though she is younger - potential roo?


Chat GPT says Langshan x Australorp or Maran x Australorp.

Thoughts? Thank you in advance for any help you can provide!!
