Good morning. I'm no expert by any means, they appear to be a Malay, Malay/ Brahma mix. The first photos have the proper head, comb, legs of Malays. The other appear to be mix with Brahma, could be Langshan, because of change in combs, wattles, and leg feathering. Langshan are also very tall. I would guess several generations of mixing these breeds to get such results. There are many rare breed hatcheries listed on this site. Good luck on your quest.
