Many of the long crowing chicken breeds originate from the Balkans from the Ottoman period. "The name comes from the ability of roosters to prolong a crow for an exceptionally long time, which distinguishes them from all other domestic and wild chicken breeds. Within the group, breeds differ with respect to the timbre, crow duration and power. Usually, the crowing itself lasts from 10 to 20 seconds, while in some Denizli and Kosovо Longcrower roosters–up to 60 seconds and more. It is believed that this mutation in chickens emerged in Asia, approximately 2000 years ago. The first reports on longcrowing roosters are from Ancient China, and several centuries later in Japan."
