Animal welfare (how the hens are cared for)
Happy and healthy hens, free from disease and stress, produce more eggs. In Australia, we have very high standards in terms of how farmers care for their hens.
In Australia, hens are housed in three different ways. Some are kept in cages in a big hen house. Some are kept in a big hen house where they are free to roam around. Others are kept in a hen house at night but are free to go outside during the day.
Farmers look after the health of their hens very carefully so that the eggs they produce are good quality. They have programs in place to make sure the hens don't get sick from diseases and to prevent them from being attacked by pests or other predators.
Most hens start laying eggs when they are between 3 and 6 months old. When they are young their eggs are small but they get bigger as the hens grow older.
Light is very important for a hen as it will determine when she will start laying eggs and how many there will be. Hens lay more eggs in Summer or Spring as there are more hours of daylight. During Autumn or Winter the number of eggs a hen will lay decreases with the daylight hours.
Hens are omnivores so they eat a wide range of foods like plants, seeds and meat. A hen's diet needs to include six main nutrients. Farmers carefully plan what the hens are fed so they are healthy and happy egg layers.
