no, only to fertilize the eggs.

Just one. \n\nVery few animals produce more than one offspring per egg.

I used to have laying hens about two dozen at any given time. An old gal that got me started said that if you want fertile eggs for hatching, so you are not wasting time using an incubator you should wait about a week. But keep in mind that a rooster will have his favorite hens much like girl-friends. To be more sure of fertile eggs it's best to separate or confine the hens with the rooster so he doesn't have a lot choices with whom to fertilize. Or pick out those hens that you've seen him with and only incubate eggs from those hens. Or you can " candle " the eggs to see if you see the " blood spot " on the yolk. This a sure method to verify a fertile egg, but difficult for the novice to do.

Roosters don't lay eggs, chickens do.

We don't actually know. If the chicken came first, an egg was needed to hatch into that chicken in the first place. If the egg came first, a chicken would be needed to hatch an egg. There is no definite answer (yet anyway).

The hen of course. Each species was sent in pair and then they multiplied. Imagine a mammal, it does not lay eggs, so it must have come as in its animal form first.

In order for an egg to hatch it must be fertilized.  Therefore, it takes two creatures to make a fertile egg.  For the chicken to predate the egg, there would have to be two chickens before the egg; a hen and a rooster.  Eggs are also often laid in batches.  Therefore it seems more likely that two creatures (not quite chickens) conspired to fertilize and lay a batch of eggs that became (male and female) chickens and when hatched they could have even more chickens.  This proves that the eggs were first.  A chicken is distinct from all other creatures because of its unique DNA and number of genes as received from two parents.  Only in the egg could the first correct set of DNA occur.  But I don't want to end an interesting argument.

None of the two. First it was the rooster then the chicken and the the egg!!!!!!

1.5 chickens lays 1.5 eggs, thus 1 chicken lays 1 egg as there is a 1:1 correspondence.\n\n1 chicken lays 1 egg in 1.5 days, so 1:1.5 is .6:1, one chicken will lay .6 or 2/3 of an egg in one day.

Depends on the bird. Usually it is inversly proportional to the size of the cache of eggs. Chickens for example lay a great number of eggs because they are flightless and pretty much defenseless. Mortality is high so the species compensates with prodicious egg laying. Interestingly this makes them an excellent livestock choice which has certainly contributed to the survival of the species.

Rooster is a male.  Hen is a female.  Chicken is lunch.

if a rooster lays an egg on top of a pointed roof witch way will the egg fall

If laying hens are receiving proper management, the most common reason for reduction of lay is a reduction of light. The reproductive state of all birds is strongly regulated by the amount of light that they receive each day. If hens are to maintain a constant state of egg production, they must be subjected to at least 16 hours of light every day. This light can be provided from sunlight, artificial light sources, or a combination.\n\nThis was cut and pasted from an article called "Why do Hens Stop Laying Eggs" (see link below).

the rooster is needed to fertilize the eggs...if there is no rooster present, then the eggs aren't fertilized.\n\nIt's very much like humans, fertilization doesn't happen every time, you can sex and not get pregnant...same with chickens.\n\ncheck out my source for more detailed information

Not generally. Most egg laying chickens are not kept with males, and so are never fertilized. Much like a woman, however, the egg still comes out, but it's not been fertilized.. so, like with humans, you wouldn't call the egg an embryo. \n\nThere have been some reports of regular eggs which have gone on to hatch, so if you cracked it open before that stage, you might be able to eat a chicken embryo, but you'd totally know it was one.
