Crocodiles build nests with rotten vegetation and leave their eggs inside. The rotten vegetation produces the heat necessary for the embryos to develop and hatch.

You can say a lot about the size of the animal and the length of development inside the mothers body. The bigger the animal inside the body the bigger it will be on the outside.
Ovoviviparity, ovovivipary, or ovivipary, is a mode of reproduction in animals in which embryos develop inside eggs that are retained within the mother's body until they are ready to hatch. Oviviparous describes animal that is concieved and born in this way.

Chickens have an actual shell. The shell along with the embryo is called an egg. Human embryos are inside a females' womb which is made of skin, not keratin like egg shells are.
Internal development is when an animal's offspring develop/ grow inside the parent, usually the female, before it is given birth to.
Seeds contain embryos to provide an energy source for the plant when it starts to shoot out of its seed. Think of it like the yoke for a chicken inside an egg. The yoke is the embryo of the egg.
