Space is not an issue here. I can and will have a separate pen for my Ayam Cemani. I have a 3 month old purebred pair. I was given "Jafar" by a local breeder because he has imperfections, i think he is a cross and she got screwed on a couple of birds. But it might just be color leakage, as the breeders here are finding it happens. She does have a GFF pair and others that she got from two breeders in California who are not 100% open as to the lineage of their birds. Whatever, they are gorgeous birds! If you want to pay the price, she sells eggs and chicks. I can put you intouch. She is not quite as spendy as GFF and others I think.
Here is Jafar..
