ovoviviparous
Warmth allows the baby bird inside to develop. Just like cooking a chicken egg...the heat from the stove allows the egg to cook.
No, blackbirds do not use external fertilization; they reproduce through internal fertilization. Female blackbirds lay eggs after mating with a male, and fertilization occurs inside the female's body. The female then nests and incubates the eggs until they hatch.
Devolopment
It changes after episode 27 and carries on until the end of the series
When it's about to hatch (go to serebii.net look up the pokemon in the egg; the species will be the same as the mother; for example, if a Houndoom laid the egg look up houndour,) look at the egg steps, clear the pedometer, and say a pokemon needs 5500 steps to hatch save the game when you've went about 5490 steps, save then walk until it hatches, if not a female, reset and hatch it again, repeat this until a female hatches from the egg
The female seahorse deposits her eggs in a pouch at the male seahorse's abdomen. He then carries them until they hatch.
The baby grows inside of the egg. If you are talking about chickens, they peck the inside of the egg until it cracks enough for them to climb out.
To protect the embryo inside it until it is fully grown and can hatch its own way out der
By a process called ovoviviparity. The mother keeps the eggs inside of her body until they hatch.
They don't, they just sit on their eggs until they hatch. Ducks will still try to care for the eggs that do not hatch, eventually they will give up.
Seahorses are one of the few animal species where the male carries the baby. The male seahorse has a pouch where the female deposits her eggs, which he then fertilizes and carries until they hatch.
No, animals that lay eggs do not have a gestation period. Instead, the embryo develops inside the egg until it is ready to hatch. Gestation typically refers to the time a mammal carries a developing fetus inside its body before giving birth.
Not really. Seahorse females deposit their eggs into a male's pouch, who carries them until they hatch. But once hatched, the babies are outta there.
A cockroach actually has eggs inside of them until the eggs are ready to hatch. Once the eggs are ready to hatch, the mother pushes them out so it is like a live birth.
Crayfish have internal fertilization, where the male transfers sperm directly into the female's reproductive system through a specialized structure called the gonopod. Once the male fertilizes the eggs inside the female, she carries them externally attached to her swimmerets until they hatch.
Are eggs** and eggs are pretty much like a woman's womb, technically the organism is living, but they are not sentient until after they hatch
No. You can not hatch an old duck egg. It must be continually kept warm and turned over from the time it is laid until it hatches. Once the duckling inside dies, it can not be revived.
