I am guessing the white one is Lavender Orpington, since the only white or lite colored chickens he has are Lavender Orpington.
I have no ideal what the black ones are, though one kind of looks; and acts, like a rooster.
The neighbor doesn't have any all black chickens, though he has some dark brown, dark reddish color and some laced or speckled.
I will probably be rehoming them all. Either to someone else or my freezer.
