What conditions do pet eggs in Pikado meet before they die? Will hatched pet eggs die?

If the pet egg is hatched and will never die, if it has been smashed, it will rise to the sky if not taken care of properly, but the body is still there. If I add weakly, it has been smashed. After opening, if you take good care of it and raise it for a long time, it will slowly increase in age and it will die of old age. . . You can also keep it in a pet house. For 2,000 silver coins, it can be taken care of for you indefinitely. The age of the pet will not increase while it is being kept.
