The New Hampshire is an American heritage chicken breed developed in the early 20th century from Rhode Island Red stock. It was selectively bred for rapid growth, early maturity, and vigor, leading to its recognition as a distinct breed in 1935. ​
 
Key Features:
Appearance: New Hampshire chickens have a rich chestnut-red plumage, lighter than the deep mahogany of Rhode Island Reds. Males typically exhibit black tail feathers, while females may have black highlights in their tail, neck feathers, and wing primaries. They possess a single comb, yellow skin, and clean, yellow legs and feet. ​
 
Size: This breed is medium to large-sized, with males weighing approximately 8.5 lbs (3.9 kg) and females around 6.5 lbs (3.0 kg). ​
 
Egg Production: New Hampshire hens are good layers, producing about 200-220 large, brown eggs annually. They are known for their early maturity and consistent laying ability. ​
 
Temperament: New Hampshires are generally friendly and approachable, making them suitable for families and small homesteads. However, they can be assertive and may dominate more docile breeds. Their temperament can vary from docile to competitive and aggressive. ​
 
Hardiness: This breed is hardy in both hot and cold climates, maintaining strong egg production year-round. They are resilient, disease-resistant, and thrive in various living conditions, whether free-ranging or in confinement.
 
Summary: The New Hampshire is a versatile dual-purpose breed, valued for its rapid growth, reliable egg production, and adaptability. With their rich chestnut-red feathers and friendly disposition, they are an excellent choice for poultry keepers seeking a dependable and productive addition to their flock.
