They might have individual temperaments. My 2 male Ayem Cemanis: One that started crowing at 8 weeks old picks fights with birds larger than himself. The other one I have not observed crowing or starting a fight, but he definitely stands up for himself. The 3 hens are shy, don’t have the large upright combs, and run away from all conflict.I have two barnyard mix males and one will likely get replaced by an Ayam Cemani male, assuming one gets along with the other male I intend to keep.
The two current males were hatched together and sorted out the pecking order early. Aside from the occasional dust up they get along great.
Were the Ayam males friendly? Neither of mine are particularly friendly, but only one has caused a few problems.
Depending on the temperment of the Ayam male, they may both get replaced by one male.
