Hoping someone has a good idea what these girls are! Despite the very different colouring, they have many similarities. Same size, small combs, similar feathering, calm, almost shy temperament. Both kind of stick to themselves, neither like to be petted or picked up. They're 16 weeks in these pictures, and haven't started laying, so no help id'ing them by egg colour. The black one's legs are almost black/slate coloured, the other one has light flesh coloured legs.
