In the vast kingdom of poultry, where feathers flutter and clucks echo, there exists a marvel of nature, a behemoth among birds—the White Sully. This colossal breed, a product of meticulous breeding and natural selection, has captivated the imagination of poultry enthusiasts worldwide. Originating from the fertile lands of California, USA, the White Sully stands as a testament to the ingenuity and perseverance of its creator, Grant Sullens. But what sets this majestic fowl apart from its feathered counterparts? Join us as we embark on a journey to unravel the mysteries and marvels of the largest chicken breed known to man.

Origins and Evolution

The genesis of the White Sully traces back to the fertile farmlands of West Point, California, where Grant Sullens, a visionary poultry breeder, sought to create a breed that embodied strength, resilience, and sheer size. Drawing inspiration from the robust Rhode Island Reds and other heavy breeds, Sullens embarked on a breeding program that would redefine the standards of poultry farming. Through careful selection and crossbreeding, Sullens succeeded in crafting a breed that surpassed all expectations—the White Sully.

Unveiling the Titan: Weirdo the Rooster

In the annals of poultry history, one name stands above all others—the legendary Weirdo. This colossal rooster, a shining beacon of the White Sully breed, attained unprecedented fame for his remarkable size and ferocity. Weighing in at a staggering 10 kilograms (22 lbs), Weirdo towered over his peers, earning him the title of the largest chicken ever recorded. But Weirdo’s legacy extends beyond mere size; his unyielding spirit and fierce demeanor made him a force to be reckoned with. Tales abound of his encounters with unsuspecting intruders, as Weirdo defended his territory with unmatched tenacity. His exploits, though legendary, serve as a testament to the indomitable spirit of the White Sully breed.

Physical Characteristics

What sets the White Sully apart from other chicken breeds is not just its size, but also its distinctive physical features. Sporting a broad frame and sturdy build, these magnificent birds exude an aura of strength and vitality. Their plumage, predominantly white with hints of red and brown, gleams in the sunlight, a testament to their impeccable lineage. But it’s not just their size that commands attention; the White Sully’s striking appearance and regal bearing make them a sight to behold in any poultry yard.

Behavior and Temperament

Despite their imposing size, White Sully chickens are surprisingly docile and sociable creatures. Known for their gentle disposition and amiable nature, these birds often form close bonds with their human caretakers. However, their peaceful demeanor belies a fierce loyalty to their flock, as they will not hesitate to defend their territory from perceived threats. While incidents of aggression are rare, it’s essential to approach these majestic birds with respect and caution, lest you incur their wrath.

Dietary Preferences

Like all chickens, the White Sully thrives on a balanced diet consisting of grains, seeds, fruits, and vegetables. However, due to their larger size and higher energy requirements, they may consume more feed than their smaller counterparts. Supplementing their diet with protein-rich treats such as mealworms or kitchen scraps can help maintain their optimal health and vitality. Additionally, access to fresh water is essential for proper hydration and digestion, ensuring that these magnificent birds thrive in any environment.

Lifespan and Care

With proper care and attention, White Sully chickens can live long and fulfilling lives, bringing joy and companionship to their owners for years to come. On average, these birds can live anywhere from 8 to 10 years, though some may exceed this lifespan with optimal care. Providing a spacious and secure coop, regular veterinary check-ups, and a nutritious diet are essential for ensuring the health and well-being of your feathered friends. By fostering a nurturing environment and forging a strong bond with your White Sully chickens, you’ll not only enhance their quality of life but also enrich your own in the process.


In the colorful tapestry of the avian world, the White Sully stands as a true marvel of nature—a symbol of strength, resilience, and unwavering spirit. From its humble origins in the heart of California to its legendary status as the largest chicken breed in existence, the White Sully embodies the indomitable will of its creator, Grant Sullens. Through centuries of selective breeding and natural evolution, these magnificent birds have carved out a special place in the hearts and minds of poultry enthusiasts worldwide.
