Rooster or hens? Australorps?

How disappointing. I got them locally

Maybe you could contact them since they are not australorps. I don't know if they would do anything, but it's worth a try.
Hopefully they are not all cockerels - australorps have some long tails, so maybe they are mixed and that is why you have the green shine. But, I don't know enough about barred rocks and mixes to know if the tail feathers would come out like that.

Australorp mix or cuckoo marans mix cockerels.
