Because a hens egg is like the egg your ovaries release...the hen laying the egg is like the ovary releasing the egg into your uterus. The only way the egg can mature is if it is fertilized by a rooster, as the only way you can get pregnant is if it is fertilized by male sperm.
Make sense?
All eggs have yokes, this is the nucleus of the cell. However, hens lay eggs without fetuses inside when the eggs are not fertilized by a male rooster.
No. Chickens will lay perfectly good eggs without a rooster. In fact, many people prefer not to keep a rooster, because they don't want to find a fertilized egg that was a little too far along.
no. they will lay without a rooster
My hens are never left with a cockeral or rooster as I own only hens (except from my chicks) and the eggs are definitely safe! :)
No, hens will lay wether they be with a rooster or not
No, a hen cannot lay a fertilized egg without exposure to a rooster. However, a hen can lay fertilized eggs up to a week after the male is taken out of the flock.
They eggs are the same size as if there is no rooster in the flock.
No, only if you want fertile eggs. The hens will lay without a rooster.
Absolutely yes. A hen does not need a rooster to produce eggs, she only produces fertile eggs when a rooster is involved. Many farm flocks do not have a rooster among the flock and egg production does not suffer in the slightest. A rooster job is to protect the flock and mate with the hens to produce offspring but the hens will continue to lay eggs with or without him.
NoAnd it's called "Laying" not "Laying on"Cockerels don't lay eggs, so improve your question by saying "Is there a breed of hen that does not lay eggs.I think he/she was asking if there is a breed of chicken that doesn't go broody, and the answer to that is yes alot of chickens have been bred not to go broody (ex.leghorn)
He makes hens eggs fertile. Hens lay eggs without a rooster, so unless you want more chickens, you do not have to have a rooster around. Roosters tend to be bad tempered and actually hens lay MORE eggs without a rooster around. Roosters are constantly bothering the hens for sex and are very aggressive about it so the hens get quite frazzled about it. Roosters can sometimes pluck all of a hens feathers out chasing her around grabbing her for sexual purposes. They also crow loudly before dawn breaks every morning for about half an hour. You can always get more hens at a hatchery.
As long as there is no rooster around to mate with the hens, you will not receive fertile eggs.
