Oh I see, what I was talking about is a unique egg level system independent from the existing adoptables level system. The adoptable's level remains as 0 until it is hatched. You can set the total number of clicks required to hatch an egg, and you may assign various egg crack stages. Adoptables in their egg stages may have different properties compared to their baby/adult forms, as you may not breed, trade or use items on eggs. Each egg stages may have different description assigned to it too.
