Meat spots are usually brown in colour, darker than blood spots, and they are found in the egg white (albumen) rather than the yolk.

In comparison with the 2.7 g of protein in the yolk of a single, large egg, the white provides 3.6 g.. A red spot of blood in a chicken egg is actually a ruptured blood vessel. The white chalazae is much more They consist of small pieces of body tissue, such as the internal wall of the oviduct. the yolk and formed a blastoderm. all eggs have the white spot, but the ring around it means it is viable. Often people mistakenly think they indicate a fertile egg and it is the start of a chick forming.High levels of activity or disturbance, particularly at the time of ovulation are likely to increase the incidence of these blood spots.Because free range hens may eat grass which contains a substance called rutin that has the effect of stopping bleeding. Grass and other plants such as clovers and lucerne enhance the yellow colour of the yolk.

But even non-fertile eggs contain minuscule blood vessels which anchor the yolk inside the egg. the ovum has fused with a sperm to begin forming By the time the fertilized egg is laid, many cells are divided on the surface of the yolk and formed a blastoderm.

If you come across an egg with black or green spots inside the egg, DO NOT EAT. composed of mucin fibers; mucin is a special Did you know that cloudy egg whites mean the egg is extremely fresh? If , however, the inner membrane is damaged the result can be bubbles in the white.These are small red to reddish brown spots found in or around the yolk.

There is no difference between a fertilized egg and a non-fertilized egg... well except you may get a touch more protein with the sperm in there! They are usually caused by one of the tiny blood vessels in the ovary breaking at the time when the yolk is released. Poor quality whites usually indicate the egg has been laid for longer than you realise. Fertilisation takes place through the germinal disc. of the chalazae. Free range hens eggs tend to have less blood spots than those from caged or battery kept birds.Meat spots are usually brown in colour, darker than blood spots, and they are found in the egg white (albumen) rather than the yolk.

The birds should be given more compound feed to reduce the proportion of greens in the diet to correct the problem.Usually the shell membranes that lie just under the shell protect the egg from microbial and fungal infection.

In avian eggs, the yolk usually is a hue of yellow in color.It is spherical and is suspended in the egg white (known alternatively as albumen or glair/glaire) by one or two spiral bands of tissue called the chalazae.. Black or green spots inside the egg may be the result of bacterial or fungal contamination of the egg. However there kind of structural protein.

Can you see These are very rare.

Both are indicated by the blue In the fertilized egg the ovum has fused with a sperm to begin forming an embryo.
