Despite the ongoing popularity of Pokemon GO, not all players know everything about it. One mere example is how eggs are stored in the inventory. They neither have dates nor locations, though there are bunch of theories within the community. Still, at the end of the day, no one knows.
According to Otakukart, a Pokemon GO player in Reddit (in the name of DamnNatureY0uScary) was able to fill in the missing puzzle piece. He was able to notice a certain pattern, thanks to this 2 km and the rarer 10 km eggs. Apparently, it's actually easier to keep track of these especially as to which PokeStop provided the only single egg.
The aforementioned Pokemon GO player suggests that whenever travelling a PokeStop (one that offers either of the above-mentioned eggs), the eggs will eventually change positions. For instance, if a player tends to get closer to a PokeStop of 10 km egg, the said egg will show right away in the inventory. It's worth noting that the latter is referring to those that are after the incubated ones.
When the Pokemon GO fan went home and/or headed away from the PokeStop that gave him the egg, it's the other (2 km egg) that moves its way to the top. Surprisingly, on his way, a PokeStop was just near him; hence he received the aforesaid egg. He then got to confirm this process after conducting a couple of experiments from time to time.
It appears that in Pokemon GO the locations of the eggs in the inventory changes accordingly. That it seems to be inconsistent with the PokeStops that provides it. So if a player would want to receive a 10 km egg, he can use the trick to know which stop will do so. This is actually an interesting pattern to try. After all, it'll help players understand and determine what kind of creature may be hatched.
