How do chickens lay eggs without sperm?
Ovulation (release of the yolk from the ovary) occurs every 24 – 26 hours regardless of fertilization (so a rooster is not needed). A hen ovulates a new yolk after the previous egg was laid. It takes 26 hours for an egg to fully form (white and shell added), so a hen will lay an egg later and later each day.
What part of a chicken does the egg come out of?
Hens are able to lay eggs without mating through a process called parthenogenesis, also known as "virgin birth". Parthenogenesis is a form of asexual reproduction in which an egg develops into an embryo without being fertilized by a male sperm.
How does a rooster fertilize an egg?
Cloaca: The cloaca is the only hole for the reproductive and digestive system of a chicken. The cloaca, also known as the vent, is where chickens poop from, where the eggs come out, and where they mate with a rooster.

The rooster lowers his cloaca, and the female inverts her cloaca until they touch.This is called the Cloacal kiss. There's no penetration involved since roosters don't have penises. During the cloacal kiss the hen opens her cloaca so that the rooster's sperm can be passed effectively from his papilla into her oviduct.
Can I eat eggs if I have a rooster?
Hens still produce eggs without marriage as long as their breeders give them food well, while fertilized eggs can be hatched because the males fertilized them. “Fertile and infertile chicken eggs are all safe to eat. The only difference is whether there is sperm or not in it,” Dwi explained.

A rooster brings order to the coop.
Chickens like structure and a “pecking order” is strictly enforced in the flock. Weaker hens defer to larger hens and, in the absence of a rooster, the most aggressive will step up to rule the roost, although the position is often disputed.

Did the chicken or the egg came first?
Scientists have unraveled the origins of human pregnancy by tracing how our early mammal ancestors first evolved to give birth to live young. They found rogue fragments of DNA that jumped around the genome millions of years ago caused switched off the processes needed to lay eggs.

The age-old riddle has finally been settled. Eggs are much older than chickens. Dinosaurs laid eggs, the fish that first crawled out of the sea laid eggs, and the weird articulated monsters that swam in the warm shallow seas of the Cambrian Period 500 million years ago also laid eggs.
How often do hens lay eggs naturally?
The chalazae are "twisted, cordlike strands of egg white" that anchor the yolk from the top and bottom of the shell membrane, keeping the yolk from getting busted before you crack the egg. In a fresh egg, the chalazae will be especially visible—so don't feel like you need to remove them.
Are brown eggs fertilized?
Breeds that are top egg producers can achieve nearly an egg a day for perhaps two-thirds of the year. Generally, a hen's reproductive cycle is about 24 to 27 hours long. As a result, a hen may get into a rhythm of laying an egg about once a day.
