What breed could potentially have laid this egg?

[jesskuh13]

First egg today...any ideas on what breed laid it? I have Easter Eggers, Australorps, and Rhode Islands. I think it's a medium size egg. TIA

How old are you hens? Brown egg would typically rule out Easter Eggers but not always.

I vote RIR. My australorps lay a very light brown, more of a tan colored egg. I remember my mom's RIRs laid a darker brown egg like yours.

Looking at the pictures I would guess Henrietta! You can always try to check:

Agreed, looking at the pictures I have no doubt its you Red's egg.
