You were right, it’s not the same species as the other eggs. So if it’s not a dragon, what is it?

And look, it’s gotten bigger! Maybe it will reach its full size soon.

It lived with the humans. The humans were enamored with this little Blue Dino. Thus, whenever it begged, they would feed it anything it wanted. Soon the Blue Dino began to eat anything and everything. Eventually, the little Dino became ferociously greedy. It began to rudely snatch food from the market stalls and even from little children. The last straw for the villagers was when this little Dino broke into the storehouse and devoured much of the foodstuff that were housed there. As a result, the villagers chased away their once harmless friend. Now, it lives with the other Dinos, happily devastating the population of the plants and animals it eats.
