This is my first time with this breed. I got "her" (I was told she was a female) in November at 11 weeks. I'm now starting to question as for the past month we have seen the Ayam Cemani mounting my larger breed hens. At first I thought she was trying to establish herself a little higher in the pecking order, but it has continued. However this last week she's making odd sounds, not crowing but making longer sounds. I'm not so sure anymore that she is a she. These aren't the best pictures as they were taken today with the wind, but her wattles and ear lobes seem larger than other photos I have seen of the Ayam Cemani hens. She/he will be 31 weeks old tomorrow.
