Not sure! Love the blue female. I don't think the roo has the right coloring, body shape, or leg color for a Dorking, but I'm not really experienced with the bantam versions.
Just throwing this out there...maybe they could both be Marans mixes?
The rooster does look like a (miniature) Birchen Marans.
Blue is an accepted color of Standard Marans & she has feathered legs.
No matter what they are, they are just beautiful birds
I would like to get a picture of the other hen on here soon. She is not laying, and is a little smaller so I think she might be younger and maybe an offspring of the two I have posted. She looks like the older hen but has silver in her neck.
