Here's a quick video of a young Ayam Cemani rooster belting out a couple crows. This is the alpha male of the flock, hence the name Dominik, and he happens to be the better looking male too.. He had a dust bath earlier and adds a little shake off before a second crow.
The Ayam Cemani is the all black chicken, inside and out! I have a flock of seven right now and will be sharing some more videos of them in the near future. This channel has temporarily gone to the chickens! lol
