What type of hen lays the jumbo or extra large eggs?

older ones. younger ones lay smaller eggs. (not kidding)

18. 1 egg per chicken per day, so 1 x 6 x 3

Eggs are laid by birds and cold-blooded reptiles. The largest eggs by far were laid by dinosaurs.

egg then chick then hen.\nThe Hen that laid the egg which developed into the species we now call the domestic chicken was slightly different from our chicken. Hence the egg came first!\n\nJ

well\nit's the same as follows:\ndid egg come first or a hen?\ni wish u find your answer.

Chickens go through a rigorous training program to "train them" to lay eggs that fit the standard size egg-cups.\n\nChickens that fail to learn how to do this are generally slaughtered for chicken meat.

Actually both are good as the egg yolk contains more protein than the white. However yolks contain considerable amounts of cholesterol and fat, and taking too much of these will cause you to put on mass - in the form of body fat!. Egg whites are almost completely pure protein, and are great for putting on lean muscle mass.

The hen. The Old Testament says that on the 5th day God created the animals, not eggs.

I have to admit, when I look at your other questions, I wonder how serious you are. You look like a bit of a joker. How do I know you won't just delete this question if I help you?\n- - - - - - - - - - - - -\n\nI have gone back to look at this question. Contrary to what others have said, this question has been examined over and over and there is a substantial literature on it. The size and shape of eggs is very interesting to people in the poultry industry, and those who must develop machinery that interacts with eggs, as well as environmentalists and others. \n\nThere are several problems here clearly. One is, there is no uniform shape to an egg. Different animals and different species produce different-shaped eggs.\n\nThe second is, there is no easy formula available for an egg shape that is well-known.\n\n\nThat said, there are lots of approximation and estimation methods available, as well as lots of experimental data and tables for different kinds of eggs. \n\nIn general, for eggs that are rotationally symmetric about an axis, the surface area \n\nA= 2*pi* {int from a to b} y(x) * sqrt[1+y'(x)] dx\n\nwhere y(x) is the curve describing the boundary of the egg, \na<=x<=b. If y(x) is analytic, then this integral can be done analytically. If not, it can be done numerically, as done by one of the references. \n\nIn the case of hen's eggs, T. C. Carter (1968) produced a 3 parameter model for computing surface area ("The hen's egg: A mathematical model with three parameters", Brit. Poulty Sci. 9, 165-171, 1968). In 1949, Romanoff, A. L., and A. J. Romanoff published a book with many formulae and approximation methods for egg surface areas called "The\navian egg" (John Wiley & Sons, Inc., New York, 1949).\n\nOne of the references approximates the egg as a prolate spheroid to compute its surface area. \n \nSome of the references produce empirical formulae for the volume and surface areas of various shapes of eggs. For example, the abstract by V. G. Narushin in the references presents the presumably empirically fit-model of egg surface area, S, calculated as S = (3.155 – 0.0136L + 0.0115B)LB, in which both L and B are taken in millimeters (obviously there is a problem with the units here). \n\nOne of the other references presents some empirically-derived formulae relating weight W of the egg to its surface area A that appear to fit quite closely (for example, A=4.835*W^0.662).\n\nI think that once you decide exactly what sort of egg you are interested in, there is a wealth of material available to investigate this further.

the chicken evolved and laid an egg.

the egg, because before hens existed there were proto-hens that laid eggs as well. One day one of those proto-hens evolved and the first hen was born.

Maybe those 3 eggs were unfertilized.  The hen that laid them may be part of the group of hens that are kept separate from roosters so that their eggs are kept unfertilized in order to sell them to markets without having to worry about the possibility of having a chick in it.  Or if there were chicks maybe they never developed.  This is why they say "Never count your chickens before they hatch".

A hen can only lay an egg if it has been fertilised. Unfertilised eggs (ova) remain within the egg. Only if the ova are fertilised do they progress further, to enclose the zygote/embryo within a calcified shell (egg) which is then laid.\nTherefore its is impossible for a laid egg to be haploid (n) because such an egg just wouldnt be laid.

The size of the egg actually has little to do with the size of the embryo within, and more to do with the amount of energy needed to be stored for development of the embryo...  A large lizard may have a small egg because the embryo only needs to develop to a certain point before it's ready to emerge into the world and obtain energy from another source.  Among birds, there are in general two types of development... one where most of the development in done in the egg and little attention is payed to the chick once hatched, and the other is where not much development occurs in the egg and more attention and care is needed to assure the survival of the chick.  Hope that helps!

Hen (female chicken) raised to lay eggs are easier to find than trustworthy people

the hen came first because God made the animal and the animal layed the egg...that'a my theory :)

The peahen lays the eggs.
