So, initially i little talk about the eggs. We all are know that the eggs are available in many colour types. Some of those are brown eggs and white eggs. Brown eggs are laid by brown-feathered chickens with red earlobes and white ones are laid by white-feathered chickens with white or light colour earlobes. Brown eggs are associated with organic, which might make them seem a healthier choice. Yes, the taste is different because more with the diet of the chicken that laid it but that has nothing to be with quality or nutritional profile of the egg.
The chickens are fed a different kind of diet which impacts the quality and taste of the egg. So if you were to feed a brown and a white chicken the same kind of food, the difference in taste would go unnoticed. Now I am going to talk about the topic of fertilized eggs. For a chicken to develop from an egg, it must be fertilized.
Given the right nutrients, hens will lay eggs with or without having been in the presence of a rooster. For an egg to become fertilized, a hen and rooster must mate prior to the information and laying of the egg.
The simplest way to tell if an egg is fertilized is called candling the egg. Candling is nothing but a process of handling a strong night above or below the egg to observe the embryo. A candling lamp consists of a electric bulb covered by a plastic or aluminum container that has a handle and an aperture.
The egg is placed against this aperture and illuminated by the light. If you do not have a candling lamp, try using a torch.
But this process is done in a darkened room. If the egg appears in opaque, it is probably a fertilized egg otherwise the egg is unfertilized. These are the technical words to define the fertilization of an egg. I cannot guarantee that all the fertile eggs will hatch but I can guarantee that the eggs to be arrive in good condition. Most of them people are buy an eggs from grocery stores and the grocery buys an eggs from chicken farms.
If you want to get the most of the eggs nutrients, then go for the fresh eggs available in the grocery store. If you bought your eggs from a commercial farm or a supermarket, however, you can safely assume that your eggs are not fertilized.
Richard Fulton, a diplomate of the American College of Poultry Veterinarians with more than 30 years of experience in poultry pathology and medicine. Identifying a Fertilized Egg From the Inside You can tell whether the farm egg you just cracked open for your breakfast is fertilized or not. Examine the egg for the germinal disc , a white spot floating above the surface of the yolk. In a fertilized egg, the germinal disk contains the merged female and male cells.
These will divide and multiply, leading to the development of a chick embryo. A fertilized germinal disk looks like a tiny white donut or bullseye—a white ring with a clear center.
If your flock includes a broody hen or two, the mama wannabes might have been sitting on an egg. Of course, if you raise only pullets and hens on your farm, there is no need to worry about fertilized vs. Your broody girls can sit on a clutch of eggs for days on end, and nothing will develop inside those eggs aside from bacteria. In fact, it is a type of a union of the genetic material of two different gametes.
Both egg and sperm carry a half number of chromosomes of a particular organism. The fusion of the membranes of two gametes is the first event of fertilization, forming a channel that allows the passage of genetic material from the sperm to the egg. Generally, when one sperm enters into the egg, the membrane of the egg becomes hard in order to prevent a second penetration by a sperm. After fertilization, the fertilized egg is activated to undergo cell division. The early stage of the development of the embryo is known as the blastocyst.
Fertilization of the egg is shown in figure 1. Figure 1: Fertilization of the Egg. The activation of the egg to form an embryo does not necessarily require the intervention of a sperm.
It can be accomplished by the intervention of chemical or physical agents to form a haploid embryo. This can be identified in invertebrates such as bees, aphids, and rotifers. Fertilization can occur in two ways: internal fertilization and external fertilization. Unfertilized egg refers to an egg that has not fused with a sperm. In mammals, it is known as the ovum. It gives rise to the embryo after fertilization. The unfertilized egg exists in the secondary oocyte stage.
