How are the eggs we eat different from the eggs that produce a chick?
356568
The chicken eggs we eat are unfertilised and not foetuses.  (Although I have heard urban myths where someone has cracked an egg and found a baby chick inside).  In natural circumstances (esp. in the wild), unfertilised eggs are rarely laid.  A rooster will fertilise a hen's egg through mating and the egg is laid and incubated until it hatches into a chick.  Farm hens produce an enormous number of eggs unfertilised for human consumption, as a result of human farming technology.

the egg was first becuz of a strange cross breed\nbut the chicken could reproduce among them selves so they did and they prospered

The chicken evolved from another egg-laying bird. The first birds evolved from egg-laying reptiles, which evolved from egg-laying amphibians, which evolved from egg-laying fish. Going back to the beginning, minute variation in the "ovulation" cycle of whatever creature first laid an egg of any type.

The eggs that are produced in a poultry farm for table purpose only, are unfertilized ones. These are obtained from a specially developed hens that are called 'layers'. These birds begin to lay eggs as soon as they become mature and for that they need not come in contact with a rooster (male bird). On an average they give one egg per day and continue to give at that rate for a year or so. When the average comes down and it becomes un profitable to maintain that bird, it is culled or killed for its flesh; but it is not of good quality and far from tender.\nFor table purpose there are different birds that are called 'Broilers'. They are not for eggs but for the flesh or meat only. It is tender and delicious.\nLastly the table eggs or the unfertilized ones are no way inferior to the fertilized eggs in nutrition but they have very good keeping quality i.e. they remain unspoilt for a long period with out refrigeration.\nOnly fertilized eggs can produce new bird after the incubation period of 21 days. There are separate hatcheries for that. Here the rooster and the hen are allowed to meet.\n'White leghorn' is a well known breed of poultry birds, One variety is only for table (broiler) and the other is exclusively for eggs (Layer).

nothing, its just that its hatched by different kinds of chickens. that is it.thanks for the points!

Chickens evolved from non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced the zygote. These changes and mutations only have an effect at the point where a new zygote is created. That is, two non-chickens mated and the DNA in their new zygote contained the mutation(s) that produced the first true chicken. That one zygote cell divided to produce the first true chicken. \n\nPrior to that first true chicken zygote, there were only non-chickens. The zygote cell is the only place where DNA mutations could produce a new animal, and the zygote cell is housed in the chicken's egg. So, the egg must have come first. \n\nSo it is Egg technically. (But that Egg is not a chicken egg) \nbut in ur question if the Egg is "chicken egg" then obviously then it is Chicken.

Well, your "male chicken" or Rooster as he is liken to be called is the one that fertilizes the egg.  With out fertilization there will be no "chicks"...\n\nJust as the male of the specie fertilizes females, you or any other woman, if not, then you simply ovulate and discharge the "egg" and there is no viable human being present.\n\nSo, let the rooster have his way with a chicken and you will have pee pees when you incubate the eggs.\n\nI wish you well..\n\nJesse

may be i can interpret your question this way.. why do chickens in the course of evolution formed in the way that they lay eggs, and in the same way why do humans give birth..\n\nin this case i can suggest you to think about the different modes of multiplications. chickens opted to go for the egg mode, which they found reliable and fit for survival. as evolution proceeded humans were formed and they were fit with the baby mode of multiplication.

This seems like a facetious question, but here's a whack at an actual answer. The Egg. Here's why: the actual chicken genus and species is for sure derived from a common ancestor with other birds and fowl, diverging through genetic (and morphological) changes over time. At some point, the "ancestor chicken" produced an offspring that would for all intents and purposes be insdistinguishable from what we now know as a "chicken" but was the offspring of a demonstrably different (but probably very similar) animal.

nutrionally, there is no difference.  There are different breeds of chickens (just like there are different breeds of dogs) and they lay different color eggs based on natural pigments in the chicken's body.  There are even blue and green chicken eggs.\nMost commercial egg laying chickens are White Leghorn (laying white eggs) and the Rhode Island Red or the New Hampshire chickens (laying brown eggs).\nThey all taste the same, but the white ones are easier to color at Easter!

Religion: God created man ( chicken) first .Than man gave birth (egg).\nScience: the chicken lays the egg. the egg does not lay the chicken. The egg is a means of reproduction for the chicken, and not the other way round.\nLogic: The chicken survives longer than the egg.\nEmbryo: The embryo developes before the gonad ( egg/sperm) are developed.

THE EGG. the chicken had to hatch from something. and the egg came from whatever bird was clucking around before the first chicken. see how simple that was? :)

Something that was not a chicken, because of a genetic mutation, laid a chicken egg.  The egg was first.  \n\nThe genetic changes that lead to our modern chickens happened slowly over several million years.  In order to answer this question, we must draw an arbitrary line between 'not chicken' and chicken.  A more realistic answer, is that small changes in the species, over time, resulted in our modern chickens.

Interesting fact.  God did NOT create chickens!  They are a human creation.  A hybrid of 2 other types of birds.  They wanted to be able to combine the tastiness of one bird with the domesticability of another, and voila, they got a chicken.

Actually this has a real answer. According to the book "Random Kinds of Factness: 1001 (or so) Absolutely True Tidbits About (mostly) Everything" by Erin Barrett and Jack Mingo the egg came first.\n\nAccording to their research chickens evolved from early Indochina birds called red jungle fowl. Mutations in the jungle fowls eggs produced things more like chickens...these bred with other bird causing more mutations producing todays chicken.\n\nSo the eggs have it!

The egg. If we draw an arbitrary line between something that's a "pre-chicken" and something that is a chicken, a pre-chicken laid an egg that had a mutation in it, which put it over the chicken line. Genes don't change during one lifespan, only in the offspring.

Hi there,\n\nDo you mean 'chick'?\n\nIf yes, then here's my answer - \nI think the chick came first, because he egg is 'back' of the chick. (I mean, a chick lays egg with the help of its posterior end)\n\nIf you mean chuck, then I have to say the egg is first because there is no such thing as 'chuck' which lays an egg.\n\nrule wid style n luv@vinny
