The hen...

as evolution progressed and species were lessened through the brink of extinction, there was over breeding (incest, inbreeding) between the families of terradactyls. Over the generations of constand inbreeding a terradactyl laid an egg which looked perfectly normal (for a giant terradactyl egg).

The father and the mother (brother and sister) took turns sitting on the egg to make sure it was nice and warm. The father (who was actually the mothers brother) seen his terradactyl wifes first boy friend (their father) so without hesitation he flew off to fend the father off (the father of the sister and brother, not the egg).

After 10's of minutes of wing to tallon combat, the father (of the egg, not the brother and sister) managed to fend off the intruder. Because he has been gone for so long (the 10's of minutes i mentioned) the egg had gone cold. "what can i do?", "my wife / sister will go crazy if he/she/it is dead"

In a panic he raced to the nearest natural spa (which was hot because of the lava flow under the earth, which caused a hot gas to go through the water etc.)

Upon managing to heat up the egg he raced back to his nest with the egg covered in heated mud. Sat their till the wife/mother/sister arrived.

a month or so later, all being forgotten there was a crack in the egg, oh what a joyess moment for both parents (brother and sister). they waited patiently as the cracks got biger and more aplenty. then *CRACKUMBACK* the top came off. After the dust settled they could then see what a beautiful baby terradactyl they had made together; but there was a problem, it couldn't fly, and had a strange coating all around it (feathers). Upon discovering it was a famale (ugly as sin, and really messed up looking (as a result of generations of inbreeding)) the father (who was a scottish terradactyl) said "it's ok Hen, i love ye anyway".

and so it was.

a hen is just a scrwed up terradactyl as a result of many many generations of inbreeding.

Scientifically proven.
