It has been shown that Styrian Chickens lay the most eggs when bred traditionally (extensively), on the farm's backyard. [5] Relatively small [6] eggs are light, of ivory colour and usually weigh 55 grams. [3] The Altsteirer is a dual-purpose breed mostly used for obtaining eggs, but also slaughtered for its good quality meat, [3] especially of ...
Hens lay a good number of small white or cream eggs. [1]: 116 They are not given to broodiness as pullets, but can be when they reach two or three years of age. The breed is fast to mature, with hens laying by four and half months, and cockerels crowing at five or six weeks. [6]: 54
Older hens gradually produce fewer eggs, and the eggs are usually larger. [1] Since the average lifespan of a pet layer hen is 8–15 years, [2] henopause has received attention as a potential problem for backyard or urban chicken farmers who are eventually faced with the decision to either slaughter older layers or keep them as non-producing pets.
A Black Java hen; the Java played a role in the creation of some of the American class breeds, such as the Rhode Island Red. The American Class contains thirteen breeds which originated in Canada or the United States. [1]: 11 All are heavy breeds, and most lay brown eggs; [1]: 11 most are cold-hardy: [2] Buckeye; Chantecler; Delaware; Dominique ...
Prolactin injection in hens provokes egg laying to stop within a few days, vitellum reabsorption, ovary regression (hens only have a left ovary [14]) and finally broodiness. [ 15 ] [ 16 ] However, attempts to stop broodiness by the administration of several hormones have failed because this state, once evoked, requires time to revert.
A new record was set when a hen laid 364 eggs in 365 days. [16] They are also known to be good nest sitters and mothers, making them one of the most popular large heritage utility breeds of chicken. Hens lay approximately 190 light brown eggs per year, with an average weight of 55 g ; [ 17 ] : 11 bantam hens lay some 160 per year, averaging 40 ...
The New Hampshire Red was bred to be a dual-purpose breed, suitable for production of both meat and eggs. It adapts well to either intensive or extensive management, and yields a meaty carcass. [8]: 192 [10]: 97 Hens lay approximately 220 brown eggs per year, with an average weight of about 55 g; [12] they sit well, and are good mothers.
Giriraja females lay a large number of eggs, 130–150 per year, with each egg weighing 52–55 grams. [1] The eggs have a good hatchability (80–85 per cent), and enable farmers to raise their own stock. Their shells are brown in color and thicker than that of other commercial eggs, and resist breaking.
