<font color='#000080'>Ok, following a discussion while i was making tea, which way do eggs come out of a hen?
Pointy end first or rounded end first.  Either way its gotta smart a bit i think.
Some biologist will come up with a sensible answer no doubt (Stevil).

I stand corrected, you're right, we never covered that in our Ornithology module.
However judging by the shape of the birds uterus the egg would most likely still come out blunt end first I reckon

You'll have to eggscuse me but I got quite eggcited about your eggclamaition about eggs. You see eggactly eggteen years ago my wife was in eggscuciating pain with an eggceedingly similar problem.  We eggperienced the pain and pleasure  (me the pleasure) of eggquisite child birth. Upon eggamination it would appear  eggstreamly easier if the hard wide, part eggpears first.

Yours

<font color='#0000FF'>The shell is added in the uterus or shell gland portion of the oviduct. The shell is composed mainly of calcium carbonate. It takes about 20 hours for the egg shell to form. If the hen lays brown eggs, the brown pigments are added to the shell in the last hours of shell formation.

In the last portion of the oviduct, the vagina, a thin, protein coating called "bloom" is applied to the shell to keep harmful bacteria or dust from entering the egg shell pores. The egg passes through the oviduct small end first, but is laid large end first. In the vagina, the egg is turned horizontally just before laying. If the hen is disturbed on the nest, the egg may be prematurely layed small end first. "Oviposition" is the act of pushing the egg from the oviduct.

When an egg is laid, it fills the shell. As it cools, the inner portion of the egg contracts and forms an air cell between the two shell membranes. A high quality egg has a tiny air cell, indicating the egg was collected soon after being layed and was stored properly. The air cell is usually located in the large end of the egg where the shell is most porous and air can enter easily.


There, my three years of biological study came to use.
