Hello, I am new to BYC...
I have only joined because of this thread !
I bought some (expensive!) Ayam Cemani last year, with a view to breeding. It turned out to be a bad year, flooding, and a dog attack lost me one of the trio, I managed to hatch 2 chicks, which died due to mosquito attacks. After that She didn't lay many eggs at all, and I got no more chicks.
I have read ALL the forum posts on this thread, and found it most interesting.... I would like to confirm a couple of things:
1. The hens lay a tinted egg, white with a slight hint of pink.
2. The breed originally became extinct, and was recreated, and reintroduced, Due to this, when breeding you will occasionally get a red-ish comb, or brown in the feathers.... This is a fault, and should NOT be bred with.
3. They do not lay many eggs, around 80 per year.
4 .The original breed did NOT have a rose comb.
5. The skin, flesh & bones ARE black/gray (like I said, dog attack!) The blood is RED.
6. They are not a big breed, somewhere in-between LF and banties.
My girl has just started laying again after winter, and I have also sourced 2 more hens

Here's hoping I have better luck this year.
Hope all your plans have been successful, and I look forward to hearing more from you all
Kind Regards
