The Hamburg chicken is a small breed—cocks tend to weigh only 5 lbs and hens about 4 lbs with slender legs and a neat rose comb. The bird comes in more than ten different varieties, including: Silver Spangled, Golden Spangled, Golden Penciled, Citrone Penciled, Silver Penciled, White, Black, and more recently-Citron Spangled in bantam form. Penciled breeds are smallest and self-colored birds are largest. There are also bantam Hamburgs, which weigh about 1.5 lbs. Hamburgs are hardy, active birds who are capable of flight and often excited around humans.
