Short answer: rarely.
Long answer: First, understand that a newly-laid egg contains only one cell. The rest is a yolk (the food source for a growing embryo) suspended in (an?) albumen (the white). So it's a little odd to talk about a whole egg being alive, but let's go with it.
The definition of "life" is a little squishy on the cell level. Something is usually considered alive if a typical one can reproduce, but a sperm cell is still considered alive before uniting with an egg cell.
So initially, the unfertilized egg cell in an unfertilized egg is alive. But after the eggshell hardens and the egg is laid, it's anyone's guess. I wouldn't be surprised if there were research somewhere on when the egg dies, but unless parthenogenesis (roughly speaking, a virgin birth) occurs quickly, the egg's probably dead.

Do penguins lay unfertilized eggs?
No, female penguins do not lay unfertilized eggs. Penguins only lay eggs if they have mated with a male and the egg has been fertilized. The male and female penguin take turns incubating the egg until it hatches.
What is an unfertilized egg located in the oogonium?
An unfertilized egg located in the oogonium is called an oocyte. Oocytes are the immature eggs produced in the ovaries of female organisms, and they undergo further development and maturation before they are capable of being fertilized.
When can a sperm fertilize an egg and why?
When a fertile sperm reaches near a mature unfertilized egg, the capability of sperm to pears through the egg cell wall and discharge its nucleus makes it possible to fertilize the egg. This union of male and female gametes to form zygote is called fertilization.
Is a male or female cell bigger?
the egg.
Does a male bee have a father?
When a queen bee lays an egg she usually fertilizes it with a sperm she received on her mating flight. However, when she lays an egg in a drone cell she will not fertilize it. Bee eggs will develop whether or not they were fertilized, but the result is very different. Fertilized eggs will always develop into a female (all worker bees are female), and unfertilized eggs will develop into a male. This means that males will only carry genes from the queen, not from any drone she mated with. Drones may not have a father, but they do have a grandfather.
Do penguins lay unfertilized eggs?
No, female penguins do not lay unfertilized eggs. Penguins only lay eggs if they have mated with a male and the egg has been fertilized. The male and female penguin take turns incubating the egg until it hatches.
Type of reproductuon in which an embryo is produced from an unfertilized egg?
It's called asexual reproduction, when there is no male contribution, or there is no male-female differentiation. Parthenogenisis

What is unfertilized egg in a menstrual cycle?
An unfertilized egg is an egg that has not met with sperm to create a zygote. If an egg is not fertilised then it is reabsorbed into the body and a female then goes on to menstruate.
Which egg of honey bees hatch in to male and which in to female?
The unfertilized eggs of the queen bee hatch into male bees, or drones. Worker bees, or females, and female queen bees hatch from fertilized eggs.
What is necessary for blood formation to begin in an unfertilized egg?
Male sperm
Does a female turtle egg need to be fertalized by a male after laid?
Turtles are not fish. The eggs are fertilized when the turtles mate, if a female lays eggs before mating then the eggs will be unfertilized and will never get fertilized.
How and where are eggs grown?
Chickens are the leading producers of eggs.
What is an unfertilized egg located in the oogonium?
An unfertilized egg located in the oogonium is called an oocyte. Oocytes are the immature eggs produced in the ovaries of female organisms, and they undergo further development and maturation before they are capable of being fertilized.
Is An unfertilized egg is recycled and returned to the ovaries?
It is expelled from the female body at the next period.
Which organ of the female reproductive system sheds an unfertilized egg every month?
The uterus has a lining of blood in it. When the unfertilized egg passes through the uterus it sheds this lining which causes the blood to come out.
