Ayam is the indonesian word for chicken; Cemani is a village near the central Javanese town of Solo, but the word cemani also means black in Javanese. The breed is found in Central and East Java, Madura Island and in Sumatra. Many crosses and variants are found.
I have concluded that ayam Cemani first came into being in Sumatra, Indonesia. Since in that same area a wild population of melanotic (black) jungle fowl exists, a good guess is that the Cemanis descend directly from this population. Because of its rather "normal" landrace type and build (unlike Sumatra or Silkie), I believe that Cemani is a quite direct descendent from these black Bankiva's, without much crossing.
It is said that the "real" Cemani is extinct, and that through crossing with ayam Kedu the so called ayam Kedu Cemani was developed. I have reason to doubt this, because Cemanis that are bred in the Kedu area are still a different type of bird altogether than the ayam Kedu. The ayam Kedu is a typical utility breed with good productivity. 
Certainly, crosses will have been made, but I strongly believe that a population of more or less pure Cemanis still exists in Central Java. This is, because pure melanotic chickens have always had a distinctive use in ceremonies and traditional medicine, in Indonesian cultural history.
Another guess is that the Sumatra breed was developed in the same area (Sumatra Island) by crossing with melanotic birds, possibly Cemanis. This would make the Cemani a very old breed, older in fact than the Sumatra.
The most important characteristic of ayam Cemani is, that it is completely black: black plumage with a greenish shine, black legs and toe nails, black beak and tongue, black comb and wattles, black meat and bones and even dark blood and organs.
Body weight for males is 1.8 kg, for females 1-1.2 kg. They have a narrow, compact body, a single comb with 7 tips, a straight, flat tail, just touching the ground. The long legs have long sharp spurs.

Japanese quail are small birds that are ideal for anybody who wants to keep their own hens for eggs but isn’t allowed to keep chickens.
You don’t need a male for the hens to produce eggs to eat, but if you want to hatch them you do.

The birds mature young, and you can tell the sex of the normal colour as early as 15 days old.
It is possible for the hens to lay by 7 weeks of age, however usually it takes 10 – 12 weeks. They need 14 hours of light to keep in lay.

The eggs may be small but they are gorgeous! They are very mild and creamy compared to a chicken egg and they make wonderful egg custards, or even just on their own.
Many people have been surprised at the taste as they were expecting them to be strong in flavour.

Housing
Japs can live in a variety of housing but sadly can not be free ranged like chickens as their homing instincts are severely lacking.
They can live in a purpose built aviary with other birds such as budgies, cockatiels, etc. They can live in an ark for chickens but the housing area must be lowered so that it is not more than 6” off the ground. Or they can even live in hutches.
I recommend giving each bird a space of 1 square foot or 900square cms.

Feeds
I feed mine on normal poultry layers meal and sometimes add some split corn for a treat. Some other quail keepers feed them on layers pellet however I find these can be too large for quail which are smaller than the average chicken. They need access to grit if fed on pellet whereas if they are fed mainly on meal they don’t need the grit.
I also give my birds treats every day. They get a variation of grated carrot, grated apple, pomegranate seeds, lettuce leaves, washed grass, bean sprouts, cucumber, live meal worms or earth worms, beetroot leaves, grated courgette and even crushed up cornflakes.
Giving the treats every day at the same time will help to train your quail to do what you want them to, like use the housing up a ramp etc.

Colours
Japs can come in various colours, there is the normal, brown, wild variety, which are the easiest to sex but there are also colours such as fawn, cinnamon, gold, white and then there are the range colours. For anybody wanting to start with quail, I would suggest the normal variety as the beginner will find these the easiest to sex and identify.
