One is inclined to assume that it might be dangerous for these precious eggs to be laid in zones of human intervention. It seems to be especially dangerous when humans are likely to come close to them. Indeed, it was only once that an egg was found within a city area. And, as a matter of fact, this egg seems to have lost its presence and its weight. Apparently it was the only one of all the eggs found that was victimized by its habitat. It could only dissolve in the eye of the artificiality of human constructions.
