In most birds, reptiles, insects, fish, and two types of mammals (the echidna and the platypus) an egg (Latin, ovum) is the zygote, resulting from fertilization of the ovum. To enable incubation the egg is usually kept within a favourable temperature range as it nourishes and protects the growing embryo. When the embryo is adequately developed it breaks out of the egg in the process of hatching. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
Oviparous animals are animals that lay eggs, with little or no other development within the mother. The study or collecting of eggs, particularly bird eggs, is called oology.
Reptile eggs, bird eggs, and monotreme eggs, which are laid out of water, are surrounded by a protective shell, either flexible or inflexible. The special membranes that support these eggs are traits of all amniotes, including mammals.
The 1.5 kg ostrich egg is the largest egg currently known, though the extinct Aepyornis and some dinosaurs have had larger eggs. The Bee Hummingbird produces the smallest known bird egg, which weighs half of a gram. The eggs laid by some reptiles and most fish can be even smaller, and those of insects and other invertebrates can be much smaller still. by:bre watch me on YouTube.com (babyb394)
Birds first start in an egg, they pop out and are taken care of until they are ready to be on their own. From there, they grow from a young bird to an older bird who starts the cycle again.
