A bird has a covering of skin and feathers.
Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
All bird eggs are hard, there is no choice. Ones without a proper shell are defective and usually won't hatch.
The bird that will crack a snail's shell on a rock is a song thrush. The song thrush also eats worms, berries and insects.
Fish eggs, commonly referred to as roe, typically have a jelly-like texture. They are generally not enclosed in a hard shell like bird eggs; instead, they are often surrounded by a soft, gelatinous membrane. The texture can vary slightly depending on the species of fish, but the overall characteristic is more akin to a jelly shell.
The shell is hard.
Bird eggs are adapted to land by having a hard outer shell that protects the growing embryo from damage and dehydration. The shape of the egg also helps prevent it from rolling away and provides structural support for the developing bird. Additionally, the eggs have a membrane inside the shell that allows for gas exchange to occur while protecting the embryo.
Grasshoppers do not have a hard shell.
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.

The tortoise's shell is their home. The shell has a hard cover and can protect them when something hard hits it. If they do not have the shell, they would have died fast.
Fish eggs, commonly known as roe, typically have a jelly-like texture, although some species may have a more firm or soft consistency. They are usually encased in a thin membrane rather than a hard shell like bird eggs. The texture can vary depending on the species of fish and the specific type of roe. Overall, fish eggs are not hard-shelled but are more often gelatinous or soft.
