By influence of the environment (the uterus, and hormones), the fertilized ovum (single cell) replicates its genetic content and divides, resulting in two cells. These two cells further replicate and divide into four, eight, sixteen, ... After multiple cycles of genetic replication and cellular division, further embryological development by cellular differentiationleads to formation of organs, and ultimately, to formation of a chicken! The more you know about the details in this process, the more incredible it seems that one cell can actually result in a living chick - or human being!
The part that would have become a chick.
does you think very human being begins as are fertilized and cell egg cell
The germinal disc. The egg is really just a single cell, until it is fertilized. The blastodisc (white spot on top of the yolk) is what will become part of the fetus when fertilized with sperm. Then the fetus feeds off the yolk to continue developing.

an egg i guess because it begins as a big cell then hatches to a chick with many cells

They were never fertalized. Therefor there was no chick in the first place.

I doubt that there is any limit to how large a cell can be. However, the cell's size really depends on the function of the cell. Generally, in the case of a single-celled microorganisms, the cells have to move materials (example, nutrients and wastes) across the cell membrane to stay alive. If the materials move in or out of the cell too slowly, for example the waste accumulates in the cell or the cell is unable to get its nutrients quickly, the cell will die. In order for the rate of diffusion of materials across the cell membrane be as efficient as possible, the cell has to increase its area of cell membrane per unit volume, which is to say, be as small as possible. As for the current largest cell, which is the ostrich egg, the function of the egg is NOT moving materials in and out of the cell surface membrane, but to protect the chick inside the egg and to contain the nutrients that will nourish the chick inside until the chick hatches. The chick needs a lot of nutrients and the chick is going to grow a lot in the egg, so the egg (cell) has to be rather large. There is also an organism known as caulerpa, which is a meter long single-celled organism, but I have no idea why is it that huge.
Chick-fil-A introduced Chick-n-Minis in 1986. These bite-sized chicken pieces are served on a small yeast roll and have become a popular breakfast item at the restaurant. The Chick-n-Minis are often enjoyed during breakfast hours and are known for their delicious flavor and convenience.
