Hendl is the Austro-Bavarian word for "chicken", most commonly in its roasted form.
Hendln are traditionally served in Bavarian beer gardens or at festivals such as Oktoberfest, and are generally eaten with a Brezen and/or a Maß of beer. They are also widely available from mobile rotisserie trucks that park near well-frequented locations such as supermarkets or large parking lots.
The standard German term is "Hähnchen" or "Brathähnchen". In East Germany it is often called "Broiler".
