I've received these as a present, so not sure of their breed nor age. They lay bluish/olive eggs (last pic, not very accurate color in picture). I've read only 3 breeds lay green eggs, so my best guess is Cream Legbar ?
They look like cream legbars to me, but maybe crossed with something? Couldn't tell you the age. Since their still laying I'd say under four years. Pretty girls though.
Legbar crosses for sure. So that'd technically make them Easter Eggers. The black one could even be an Olive Egger [LegbarxMarans, in this case], if she lays that olive looking egg.
