Guess Who?
 is a two-player character guessing game created by Ora and Theo Coster, also known as Theora Design, that was first manufactured by Milton Bradley, in 1979, now owned by Hasbro.
 It was first brought to the UK by Jack Barr Sr in 1982.
The California Red sheep is a breed of domestic sheep developed in the United States in the 1970s.
 It is so named because its lambs are born all red, and retain this color in their faces and limbs in to adulthood.
 In the early 1970s, Dr. Glenn Spurlock of Davis, California crossed Tunis sheep and Barbados Blackbelly sheep, and the California Red is consequently a dual–purpose breed with many of the qualities of its forebears, the out-of season breeding qualities and fleece of the Tunis and the heat tolerance and carcase quality of the Blackbelly.
 Spurlock actually set out to create a new hair sheep like the Barbados Blackbelly, but though he failed to do so — California Reds have reddish tan hairs intermingled with white wool.
 — he and other breeders continued to keep developing the strain anyway.
 The California Red can lamb out of season, thus being able to produce multiple lamb crops in a year.
 It also functions well in hot weather, and is polled in both sexes.
The history of the domesticated sheep goes back to between 11000 and 9000 BC, and the domestication of the wild mouflon in ancient Mesopotamia.
 Sheep are among the first animals to have been domesticated by humans, and there is evidence of sheep farming in Iranian statuary dating to that time period.
 These sheep were primarily raised for meat, milk, and skins.
 Woolly sheep began to be developed around 6000 BC in Iran, and cultures such as the Persians relied on sheep's wool for trading.
 They were then imported to Africa and Europe via trading.
The Royal White is a breed of domestic sheep in the United States developed by William Hoag at Dorpcroix Sheep Farm in Hermleigh, Texas.
 It is a hybrid breed that is bred to produce more meat, less fat, and less wool with the goal of producing lean tender meat.
 The breed is disease-resistant.
 Royal White sheep outgain goats and produce more meat than Dorper and Katahdin sheep (wool-hair types).
 The meat is tender with a mild sweet flavor.
 The leather is of garment quality and can be split.
 The breed was created using traits of St. Croix and Dorper and then their negative traits removed via selection over many years.
 The Royal White grows a hair with a down undercoat in the fall and naturally sheds its fiber in the spring, thus the cost and expense of shearing is eliminated.
 This is the first new breed of sheep in the United States in over twenty-five years developed for high performance and low maintenance.
Battle Sheep is a 2010 board game developed by Francesco Rotta.
 It has been published by Blue Orange Games, HUCH!

The Polypay sheep breed is a white, medium-sized sheep which was developed in the 1960s at the U.S. Sheep Experiment Station in Dubois, Idaho.
 In general, Polypay sheep are noted for being a highly prolific, dual-purpose (meat and wool) breed.
Sheep farming is a significant industry in New Zealand.
 According to 2007 figures reported by the Food and Agriculture Organization (FAO) of the United Nations, there are 39 million sheep in the country (a count of about 10 per individual).
 The country has the highest density of sheep per unit area in the world.
 For 130 years, sheep farming was the country's most important agricultural industry, but it was overtaken by dairy farming in 1987.
 Sheep numbers peaked in New Zealand in 1982 to 70 million and then dropped to about 27.6 million.
 There are 16,000 sheep and beef farms in the country which has made the country the world's largest exporter of lambs, with 24 million finished lambs recorded every year.
Easycare is a breed of sheep developed in the 1960s in the United Kingdom for meat.
 It was derived from Nelson Welsh Mountain sheep (a Welsh Mountain and Cheviot cross) which were crossed twice to the Wiltshire Horn, which is a wool-shedding breed.
 The progeny were selected for: wool shedding, no horns, and easy-care traits.
 Most animals in the wild thicken up their coats in winter and then moult when spring comes, but many modern sheep breeds were selectively bred for thick coats which are retained for shearing.
 With the decline in the worldwide wool markets, a thick coat is now less desirable, especially where the cost of shearing is higher than the value of the wool produced.
 In this respect, the Easycare breed is an interesting reversal of centuries of practice in sheep breed development as the sheep naturally shed their coats in spring, a process called rooing.
 Like many other sheep, Easycare sheep cannot live without the necessary grooming that is shearing every now and then.
This is a list of lamb and mutton dishes and foods.
 Lamb and mutton are terms for the meat of domestic sheep (species "Ovis aries") at different ages.
 A sheep in its first year is called a lamb, and its meat is also called lamb.
 The meat of a juvenile sheep older than one year is hogget; outside North America this is also a term for the living animal.
 The meat of an adult sheep is mutton, a term only used for the meat, not the living animal.
Sheep shearing is the process by which the woollen fleece of a sheep is cut off.
 The person who removes the sheep's wool is called a "shearer".
 Typically each adult sheep is shorn once each year (a sheep may be said to have been "shorn" or "sheared", depending upon dialect).
 The annual shearing most often occurs in a shearing shed, a facility especially designed to process often hundreds and sometimes more than 3,000 sheep per day.
