What breed is this?

Im new to this site and not sure if i am posting in the correct place. Can anyone help me identify these black & black/white chickens? I know the ones in the background are Amerucaunas. One of the black ones looks almost solid black, the other looks multi colored with blue/green and yellow/orange in some spots.
Thanks in advance!

The black and brown one is a black sex-link, the black one is an australorp, and the barred one is a barred rock.

I think both black birds are black sex links. They both have the tell-tale red/gold feathers on the chest.

The black and white bird is a barred Rock.
