Figure 1. Feathering types in ten-day-old chicks.Left: Fast normal-feathering chick. Right: Delayed-feathering chick carrying sex-linked K gene. Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
Hens crave privacy and darkness when laying eggs, so plan for at least one nesting box for every four or five hens. A box that measures 14"W-by-14"H x 12"D will give even a big gal plenty of room.
Cannibalism in poultry. Cannibalism in poultry is the act of one individual of a poultry species consuming all or part of another individual of the same species as food. It commonly occurs in flocks of domestic hens reared for egg production, although it can also occur in domestic turkeys, pheasants and other poultry species. [1]
The RSPCA "Welfare standards for laying hens and pullets" indicates that the stocking rate must not exceed 1,000 birds per hectare (10 m 2 per hen) of range available and a minimum area of overhead shade/shelter of 8 m 2 per 1,000 hens must be provided. Free-range farming of egg-laying hens is increasing its share of the market.
Root-knot nematode females lay eggs into a gelatinous matrix produced by six rectal glands and secreted before and during egg laying. [19] The matrix initially forms a canal through the outer layers of root tissue and later surrounds the eggs, providing a barrier to water loss by maintaining a high moisture level around the eggs.

Here’s a closer look at the facts. CLAIM: Chicken feed companies have altered their products to stop backyard hens from laying eggs and drive up demand for commercial eggs. THE FACTS: U.S. egg ...
Description. Although daily egg production starts to tail off after one year old, it may continue until 5–7 years old. 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 ...
Sex-links[1] are crossbred chickens whose color at hatching is differentiated by sex, thus making chick sexing an easier process. Sex-links come in several varieties. As hybrids of laying or dual-purpose breeds infused with extra vigor via heterosis, sex-links can be extremely good egg-layers which often produce 300 eggs a year or more ...
