Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The incubator is recorded being used to hatch bird and reptile eggs. It lets the fetus inside the egg grow without the mother needing to be present to provide the warmth. Chicken eggs are recorded to hatch after about 21 days, but other species of birds can take a longer or shorter amount of time. [10] Incubators are also used to raise birds. [11]
The sterilized eggs are washed and transferred to a plate of agar containing food for the worms. C. elegans consumes bacteria, so before the eggs can be transferred to the plate, the food must be killed by either heat or irradiation. This method for creating germ-free nematodes has the added benefit of age-synchronizing the worms, so that they ...
The earliest incubators were invented thousands of years ago in ancient Egypt and China, where they were used to keep chicken eggs warm. [1] Use of incubators revolutionized food production, as it allowed chicks to hatch from eggs without requiring that a hen sit on them, thus freeing the hens to lay more eggs in a shorter period of time.
Egyptian egg ovens are typically brick structures, often created from mud. [2] In Egypt, the ovens varied in size depending on the area served, with the largest having a capacity of 80,000 eggs. [4] Bricks of cow or camel dung fueled the incubators, [4] burning in the upper cells and emitting heat to the lower cells. Heat was regulated with ...

The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control. As of 2019, only contraceptives are commercially available.
