Do Black Jersey Giants have green tinting to their feathers?

[sunny & the 5 egg layers]

I have 2 black chickens and I thought they were Black Australorps but one is a lot bigger then the other and they are both the same age (15 weeks). They both have a green tint to their feathers. Is it possible the bigger one could be a Black Jersey Giant? I can get pictures if needed. Thank you.

Yes, and they're beautiful with that green glint!!

The bottom of JG's feet are yellow, btw. BAs are white on the bottom of their feet.

Any black chicken should have a green sheen to it's feathers.
