Am I correct in my guess that she is a black sexlink? She was sold as a "speckledy" (RIR X Maran) but she doesn't look like any of the pictures I've seen of that breed. I Google lensed her, and she seems to be a black sexlink, but I figured I would ask some chicken experts rather than just go off of Google lens, as we all know that isn't always the most accurate
Sorry for the poor quality pictures, my chickens never stay still for pictures, lol.
