Yes, there are 2 sellers that sell penedesenca eggs on eggbid and i just purchased the wheaten color from one of them.
I put 8 of the eggs under my best game hen who was just hatching and she only hatched one. It looked great but the other eggs did not have a developed embryo inside when i cracked them open.
I put another 5 or 6 eggs in the bator with some marans and i couldn't be sure if any of those hatched or not, had a poor hatch there too.
i don't recall black penedesenca at eggbid but they may have them
Wish I could offer you a link or source. I have only come across the white or partridge variety and I found those on eggbid.com. Will keep you in mind in case I ever see black Penedesencas.
