they aren't born yet so they don't need to breath.
No. To drown the chicken would have to breathe.
Yes, crocodiles do hatch from eggs. Female crocodiles lay their eggs in nests and cover them to protect them. The eggs hatch after a couple of months, and the mother helps the hatchlings to the water.
If you have seen Jurassic Park, they resemble the velociraptor that had just emerged from it's egg - big reptilian eyes, large head compared to body.
A baby turtle may squeak inside its egg just before hatching. This soft sound is believed to be a way for the hatchling to communicate with its siblings and possibly with the mother as well to coordinate hatching.
No, a baby duck egg that is cold is not alive. Because the little egg with the baby duckling inside needs heat and warmth to survive. They are just like humans without air they can't breathe and without warmth they could freeze to death and without food they could starve to death. So no if a little duckling egg is cold it is not alive.
yes
A few minutes before they hatch, they start to chirp or squeak. When the mother or father guarding the nest hears this, she digs them out. They use a hard front tooth called the egg tooth to break out of the egg.
the mother hens occationally may break the egg shell while the baby is hatching to help the baby hatch. I'm pretty sure the egg shell will not harm the mother hen much.
Snakes, crocodiles and turtles are egg laying reptiles. They are not mammals, as they don't suckle their young from their mother's milk.
It depends on the species. Nile crocodiles are around 40cm when they first come out of their egg.
When the baby chicks are developing in the egg shell, they need to breathe. The pores in the egg shell allows an exchange of good air with the bad air. A side effect to this. The pores allow moisture to escape from inside of the egg.
Yes, developing bird embryos can breathe while inside the egg through a specialized structure called the chorioallantoic membrane, which helps exchange oxygen and carbon dioxide with the environment. This membrane also allows for the expulsion of waste products.
