All came from "Black Australorp" bin....

EE, Sussex, Wellsummer or something else?!?

No idea what these might be...

It would be useful to know what other birds the hatchery or breeder sells to make a more accurate guess.
However,
The chicks in the first photo looks like they may have some Araucana in them and the second photo sort of look like a non white variety of leghorn.

What is most likely though, if you bought them as layers in AUS (Unsure if I can check location), is that all the chicks you bought are a cross of Australorp, Isa brown, and Leghorn.

Interesting!
I'm in PA. We got them from the Rural King store so I'm not sure which hatchery they came from.

I feel like the first two maybe EEs, in the 2nd picture the one to the right also looks like an EE. I'm not sure on the other one though.

I am hoping they are EE's!
