Incubation refers to the process by which certain oviparous (egg-laying) animals hatch their eggs and to the development of the embryo within the egg. The most vital factor of incubation is the constant temperature required for its development over a specific period. Especially in domestic fowl, the act of sitting on eggs to incubate them is called brooding. The action or behavioral tendency to sit on a clutch of eggs is also called broodiness, and most egg-laying breeds of poultry have had this behavior selectively bred out of them to increase production.
A wide range of incubation habits is displayed among birds. In warm-blooded species such as bird species generally, body heat from the brooding parent provides the constant temperature, though several groups, notably the megapodes, instead use heat generated from rotting vegetable material, effectively creating a giant compost heap while crab plovers make partial use of heat from the sun. The Namaqua sandgrouse of the deserts of southern Africa, needing to keep its eggs cool during the heat of the day, stands over them drooping its wings to shade them. The humidity is also critical, because if the air is too dry the egg will lose too much water to the atmosphere, which can make hatching difficult or impossible. As incubation proceeds, an egg will normally become lighter, and the air space within the egg will normally become larger, owing to evaporation from the egg.
The burrowing owl (Athene cunicularia) is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open dry area with low vegetation. They nest and roost in burrows, such as those excavated by prairie dogs (Cynomys spp.). Unlike most owls, Burrowing Owls are often active during the day, although they tend to avoid the midday heat. But like many other kinds of owls, burrowing owls do most of their hunting from dusk until dawn, when they can use their night vision and hearing to their advantage. Living in open grasslands as opposed to the forest, the burrowing owl has developed longer legs, which enables it to sprint as well as fly when hunting.
Burrowing owls have bright eyes; their beaks can be dark yellow or gray depending on the subspecies. They lack ear tufts and have a flattened facial disc. The owls have prominent white eyebrows and a white "chin" patch which they expand and display during certain behaviors, such as a bobbing of the head when agitated.

Incubator: Egg Hatching - How Does It Works - Full Documentary - NatGeo TV An incubator is a device simulating avian incubation by keeping eggs warm and in the correct humidity, and if needed to turn them, to hatch them. Reginald Carl A. Sanchez invented this incubator for the eggs even if there is no hen to hatch it. Read More: https://en.wikipedia.org/wiki/Incubator_(egg)
Prior to intubating China, we had masked him down with isoflurane inhalational anaesthetic. Birds response to gas anaesthetic very well. They are easily gased down and wake up quickly. So we prefer to use gas anaesthetic than any intravenous drugs these days.
We had the privilege of incubating two eggs of Athene cunicularia (burrowing owl) in our lab of avian diseases. These were laid at the owl research center of Instituto de Ciências Biológicas (ICB-UFMG). Tivemos o privilégio de poder incubar dois ovos de Athene cunicularia (coruja buraqueira) em nosso laboratório de doenças das aves, após a postura no centro de pesquisas de corujas do ICB-UFMG.
Clinics of Avian Leukosis Disease Rous demonstrated that sarcoma is an infections disease. Over the years this obvious observation was replaced by a view that sarcoma is genetic disease which is the essence of the somatic theory of cancer SMT. Two theories explain the nature of cancer: Dogma (SMT): Rous sarcoma virus triggers a gene which causes sarcoma. Virus theory: Rous sarcoma virus causes sarcoma. Clinically somatic mutation theory (SMT) makes little sense since it ignores manifestations of a viral infection in which sarcoma emerges. At best it may be regarded as an incomplete theory which fails to explain the infectious phenotype. I shall now describe the clinics of a viral disease, avian leukosis, in which cancer emerges and show where SMT fails. Lymphoid leukosis viruses ...

Hens usually leave their nest two or more times each day to feed and relax. Biologists call this time off the nest an incubation break or recess and typical breaks last anywhere from 30 minutes to five hours. Hens are careful to cover their nests before they leave to prevent detection by avian predators like crows, gulls, and ravens. Smaller species, like blue-winged teal, may take six or more short incubation breaks in a day.
What's Inside Those Eggs? All birds lay eggs and are known as oviparous which means producing eggs that hatch after exclusion from the body. An obvious advantage is that the female bird does not have to fly around with the weight of the developing young inside her. Eggs begin as three parts, the shell which we can see, and yolk and albumen (egg white), which we cannot see. The yolk contains the fertilized egg cell from which the embryo forms, and is rich in proteins and fat that are the food required by the developing embryo. The albumen is the source of amino acids and minerals and surrounds the yolk. The egg shell not only protects the developing embryo, but is porous and allows the passage of water vapor, ozygen and carbon dioxide, thus permitting the eagle chick to breathe. A young bi...

Here is the original Canadian news clip way back when, covering Dr John Davidson's amazing story and the benefits of fertilized incubated avian egg extract, YTE. ***DO YOUR RESEARCH***, as (Young Tissue Extract) is not all the same! Make sure you source a product that contains authentic fertilized & incubated avian egg extract from Norway. Why? 1. These hens are only required to have 1 vaccination unlike chicks here in the USA that are required by law (FDA, USDA) to have up to 15 vaccinations before then can be commercially sold. Many of these vaccinations in the USA hen eggs are still HOT even after pasteurization! 2. You only want to consume the Norway YTE that is organic, free range, fertilized, and incubated for a full 9-10 days. This insures the highest quality and quantity of live si...
