I'm not sure they're the same breed. The one on the right looks like a generic production red hen, the one on the left looks to have a more partridge-ish color. Better pic would help.
Yes, I'd say those are Production hens after what I have learned from BYC. I have three of them. Two of mine have some white on their tails. The third is all red. Thanks to BYC for the breed info. I was confused. Couldn't figure out if they were RI hens or NH Reds. Come to find out they are a mix of both as a Production. I like mine lots. They are pretty smart and love treats. They are rather calm and easy to handle. Enjoy those pretty girls of yours.
