The egg animals are: emu, sea jay, robin, octopus, and chicken.

1. Emu

Emu eggs are the second largest bird in the world after the ostrich, which is native to Africa. Emu eggs have a very beautiful appearance and can be light or dark green, weighing 450-650 grams. Unfertilized emu eggs are edible, and one emu egg is equivalent to about 10-12 eggs.

2. Sea jay

The blue eggs of the sea jay possess numerous spots, but not only do these eggs stand out in color, they are also irregularly shaped. Sea jays tend to incubate their eggs on steep rocky walls. The appearance of the jay's eggs is much more interesting compared to those of other birds because they are not as symmetrical, and this shape can change the egg's center of gravity.

As a result, the eggs are less likely to break when a gust of wind blows or the jay moves carelessly. Because the asymmetry would make it easier for them to stop or roll into the abyss, they would be noticeably slower.

3. Mockingbird

The blue color on the top edge of a mockingbird's egg protects the fetus from overheating and exposure to ultraviolet radiation. The darker shells of other bird eggs allow more heat to pass through, while the white shells reflect heat. The blue shell is a compromise that allows the egg to maintain an optimal temperature.

4. Octopus

Octopus eggs look somewhat similar to milk drops. Females will keep the eggs for months, sometimes more than a year, chasing away predators and periodically removing sludge and dirt from the eggs. During this time, the female octopus eats nothing. Because of this, by the time the baby octopus emerges, its great mother has died of exhaustion.

5, chicken

Chickens are a kind of poultry, domestic chickens originated from the wild chicken, its domestication history of at least about 4,000 years, but not until around 1800 chicken meat and eggs became mass production of goods. Types of chickens include turkeys, crows, pheasants and so on. And the chicken is also a genus in the 12 zodiac signs.
