EGG QUALITY - EGG SIZE OR WEIGHT

• Each species of bird has its own standard egg weight. Similarly the egg weight vary between breed and age of the bird. Heavier birds produce heavier egg.
• A normal chicken egg weighs 55-60gm depending upon the breed and age. The chicken egg will be about 1/30^th of the hen's body weight.
• In case of ducks, the egg weight ranges from 65-70gm, depending upon the breed. When compared to chicken, ducks lay heavier eggs which will weigh 1/25^th of its body weight.
• Goose lay eggs weighing 130-200gm, depending upon the breed.
• Japanese quail eggs will weigh around 10gm, which will be about 1/15^th of its adult body weight. When compared to body size, Japanese quail lay heavier egg than other species.
• Turkey egg will weigh 65-70g, ad it is only about 1/60^th of its body weight. In all species of birds, older birds lay heavier eggs than younger birds. Record the weight of egg provided to 0.1gm accuracy using triple beam balance.
• Some times the egg size will be extremely small or large as in the case of yolk less/ double yolked eggs which are difficult to transport because they will break during transit. They are sold in the farm itself.
