What breed are this?

Several pictures of each, showing leg color, comb type, and body type would help; but from your pic I'm going to guess the closest is an Easter Egger, the middle a Silver Penciled Plymouth Rock, and the one in back a Black Australorp.

Where did you get these from? A hatchery? If yes, which one? That will help narrow down the possible breeds.

Actually, does the middle bird have feathered legs? If yes, then it is most likely a Dark Brahma.

The one up front is an ee the legs are as green as a shamrock. The middle one also looks mixed. A better picture of each of them would make confirmation a bit easier
