Thanks for the responses everyone! So the consensus is that Henrietta is Barred Rock! So we should expect brown eggs.... There is a chicken coop on the property and we keep food in there for her that she eats, but if we get close to her, she heads for the spruce trees. So there is no possibility...
Henrietta came with our new home... She is black with white speckles and a short comb. She is very wary of humans... but likes hanging with the horses. She is a good flyer -- she chooses to roost every night in our Colorado Spruce trees. A great forager and obviously cold hardy as she is...
