Egg
Definition: egg
egg: 1. A reproductive cell produced in a female mammal by the ovary which, if fertilized by male sperm, becomes an embryo. 2. A fertilized ovum of an animal such as a bird, fish, reptile, amphibian, or insect, protected by a membrane layer in which the embryo continues developing outside the mothers body until it hatches. 3. A round object laid by female birds, with a hard calcareous shell forming a case containing albumen and yolk. The young bird grows inside the egg until it hatches. Understanding egg development and health is crucial for poultry farmers to ensure high-quality production.
