Do chickens lay eggs even if they aren't impregnated?

Question

And if they are, then the egg will have an embryo in it, but if not, it will just be the white and yolk like the kind you get a your grocery store?

Answer 1

Yes, the male shoots his goods on the eggs after they're laid. Just like fish. That's why egg farms are only hens. No c0cks allowed.

Sorry "All hat", but I seen it on Discovery. Check your facts. Just going on what they said. You disagree, write them. Are you a farmer? Didn't think so.

Answer 2

When you buy the white eggs from a store, these come from chickens that are kept in small cages. The cages are 2 x 2, and 3 or even 4 hens are kept in each cage. The breed, called a leghorn, is only raised for the eggs, and the newly hatched out males are culled at birth. Fertilized eggs don't last as long as infertile eggs, and anyway, egg factories won't have room to keep chickens of both sexes together in a large pen or barn.

The light is kept on continuously for the young hens called pullets, and also for the laying hens. This stimulates their pituitary gland which in turns tells them to start laying because they think that it is spring.

The vast majority of hens never even see a rooster and spend their laying time, about 2 years, in a small cage with other hens.
In order for the eggs to be fertile and hatch, you need a rooster for no more then 12 hens. You can find hatching eggs by putting up an ad at a store that sells farm animal food. There might also be a livestock auction. The local Tractor supply store near me sell incubators. It takes 21 days for chicken eggs to hatch and 101 degrees.

The blood spot in an egg is just that, a blood spot. This happens when a blood vessel in the hen where the eggs are formed, starts bleeding. The shell forms around the yolk, enclosing the spot and all.

When I candle the eggs at 3 days to throw out the infertile ones, I will see a small heart starting to beat, and sometimes a black spot where the eyes are forming. Later I will see blood vessels forming just inside the shell.

Does a woman need a man to have "that time of the month?"

So you see, a male rooster isn't needed for a hen to lay eggs.

Answer 3

A hen will lay eggs regardless of whether or not there is a rooster around.

However, if there is a rooster, then they will mate, and the sperm is encased inside the egg. It is then laid, and it looks just like an egg that you would buy at the grocery store, both inside and out. At this stage there is no embryo.

If the egg was incubated, either by a hen or in an incubator (making sure the temperature, humidity and turning is right) then 21 days later, a chick would hatch.

The eggs that you buy at the grocery store are laid by hens that have never seen a rooster, let alone mated.

Answer 4

Chickens lay eggs whether there's a rooster in the house or not. I have a rooster, so I know the girls are all bred, but I can't tell any difference in the eggs from the grocery store ones.

You have to actually incubate the egg for an embryo to form. Otherwise it's just a plain old egg. Eggs can sit in the nest for up to 10 days without developing. After that they won't develop at all. Hens just keep on laying until they have a nest full, and then they start to set. All the chicks will start to develop the day she choses to set.

Answer 5

Correct. The eggs from the grocery store are not fertile. Other types of birds can lay infertile eggs also. If you ever see blood in the yolk then this is evidence of an actual embryo (impregnation)

Answer 6

Yes. Most if not all birds lay eggs even if there is no male around. You can't have an embryo without a male. A bird cant impregnante itself. The eggs at the market are unfertilized.

Answer 7

yes at 19 weeks the hen will start to lay she has all her eggs they develop prior to laying at 72 weeks they have used their best eggs and are ready for slaughter. There will only be an embryo if there is a rooster doing his thing... ehm you know... grocery store eggs are layed by hens that never see a rooster.

Answer 8

Chickens will lay eggs every week. Normally eggs are not impregnated, they are not fertilized and do not contain any embryo. If they are impregnated, these embryo eggs normally will not appear in your supermarket or mini marts for they will be used for rearing.

Answer 9

Yes they lay eggs even if they are not inpregnated. And sometimes you may get a fertilized egg in your carton at the grocery store. That is why you never open and dump a raw egg into your cake mix or whatever. You always put it in a container first. I have gotten feritlized eggs before and you can tell because they have some blood inside...yuck.

Answer 10

yes they can lay eggs without being impregnated. its the ones you buy at the store. they are always unfertilized

it would be gross to buy an egg that has a chicken fetus in it

Answer 11

Yes...chickens lay eggs regularly without any help from the rooster.
