Sandhill Preservation says they're sold out for 2025 but you might still reach out to them. Maybe they have a few chicks at random times or they can tell you the best time of year to order to get them.
"Black Penedescenca- Black Minorca-like chicken with a unique single comb that has almost a crown at the back side. They lay a dark brown egg. Their behavior is very flighty and is similar to a Leghorn. They have an unusual comb - - - single in the front with multiple lobes at the rear. Our strain tends to not have the pure white earlobes. We strive to select for darkest egg first, comb type second. Our males tend to have bright, white earlobes and the proper combs. Hens tend to have less white earlobes and not always the best combs. These have not yet been admitted to the APA Standard. We have maintained this breed since 2005. Chicks $10.00 each (Maximum of 5 per hatch)SOLD OUT FOR 2025."
