86. Identifying Breeds of Poultry

87. Breeds, Varieties, Types & Classes
There are no breed registries for poultry unlike other farm animals.
Most commercial producers develop their own “breeds” through crossbreeding different strains/breeds.

88. Breeds, Varieties, Types & Classes
Breed- group of related fowl that breed true for a specific trait
Type- purpose for which it is breed (meat or egg type)
Classes- geographic origin (Mediterranean, American, English and Asiatic)

89. Egg Producers Layers- chickens that produce eggs
White egg producers- small in size
White Leghorns- white plumage
Brown egg producers- larger birds that are not as economical as Leghorns
Rhode Island Reds- dark red plumage
New Hampshires- red plumage
Plymouth Rocks- white plumage

90. White Leghorns (white egg)

91. Rhode Island Red (brown eggs)
