My guess is easter eggers. Sometimes they have wattles instead of beards or a mix of both. If the hen lays blue or green eggs then they are definitely easter eggers.
She lays a light brown egg and has neither wattles or a beard. I don't know that the rooster is the same breed as she is. Her coloring is so very similar to the brown leghorn but she has a completely different comb. Her body structure is different as well, she is more plump compared to the leghorns.
They both look like non-bearded Easter Eggers to me. Easter Eggers usually lay blue or green eggs, but one of their defining characteristic is that they lay colored eggs--including brown.
They are both mixed breeds. Others are saying EE- very reasonable guess as they are extremely common..... but to me they have the look of American/Old English Game mixed with a dual purpose bird. Possibly Buff Orpington, New Hampshire or less likely, Rhode Island Red.
It's the tight, clean Game-ish faces with pea combs and the very long tail on a 'heavy' body. Most EE have short or medium tails. Long tails are characteristic of Games.
The hen especially has strong Game blood look about her. As if she's maybe 3/4 game with the extra weight from the dual purpose ancestor?
