How does a chick get oxygen inisde an egg?

Eggs are not a solid vacuum or impermiable.
They are quite pourous and allow oxygen to enter. Although the chicks, much like human embryos do not use lungs to process it.
Below is a good article on it

The eggshell's pores are identifiable as minute indentations on the surface of the shell and are connected to very fine air channels that run straight through the shell. These channels are large enough to allow air to reach the embryo but small enough to slow the evaporation of moisture from within, and act as a second line of defense to prevent the infiltration of organisms from without. Even though the cuticle and air channels help reduce water loss by the egg, the humidity of the air surrounding an egg plays a role in the survival and development of the chick. A parent bird's body provides enough moisture to keep the eggs from drying out; an artificial incubator must always include a water source so that the air is not only warm, but moist.

Fredric Cohen (1959 advert- ) noted that, had the egg come first, there could have been no fowl (fowl) to place it, take a seat on it and shop it heat, so a stay chick could under no circumstances have hatched from it. So the egg desires a fowl. The question now's the place did that first fowl come from? If only an egg this is laid with the help of a fowl and which will hatch right into a fowl could be seen a fowl egg: Then the 1st fowl got here from a distinctive form of egg (no longer a fowl egg) and laid the 1st fowl egg. thus eggs (greater often than no longer) got here first, the fowl got here after, and the fowl egg got here final.

there is an air chamber inside the egg and the shell is porous.... you can see the air chamber when you peel a boiled egg. it is at the more rounded end of the egg between the shell and the membrane. (that thin white layer of "skin" that you peel off the hardboiled egg)

Shells are porous, which is why eggs will keep in your refrigerator longer if you dip them in vegetable oil. It seals the shell to keep the air out.
