There is no excretory material inside an egg. Excretory material is produced when materials are consumed that the body cannot use. The yolk inside the egg is for the nourishment of the growing chick. Since there is nothing in the yolk material that cannot be used, then there is no waste material to be disposed of. There will be no excretory material until after the chick has hatched and has eaten and digested its first solid food.
