Curbstone Vally Farm recently posted a very in-depth discussion on the history of the Dark Brahma breed. It's complicated, to say the least.
One of my 2.5 month old pullets (Bella) was labeled as a Brahma when I brought her home. She was black and white when she was little:
But now, she's completely black with only a dot of white on her wing tips. I love how the shiny black feathers look like iridescent green, blue and purple in the sunlight.
Anyway, the Curbstone post has lots of historical pictures of Dark Brahmas, such as this one:
All of the Dark Brahmas were patterned black and white from what I can tell. But Bella doesn't look like that. Maybe she's not a Brahma? Maybe she's not old enough to show her "mature" pattern? (This is what Clare at Curbstone Valley Farm believes, and she's probably right.) I guess I'll just have to wait and see!
