You can check the stuff in my pinned guide in the Team Showcase section and hatch an Egg in a few seconds after getting it. Just, uh, back up your save in advance. Save file corruption with that stuff is very unlikely, but it can't hurt to play it safe. Throw me a PM if you need help with any of that stuff explained there.

Actually i know all of these you said. I have replayed this game three times.

But in my current playthrough, i want to hatch the eggs a bit earlier and train them easier.

@Etesian I don't take the risk. Sorry, just had my problems with save files reborn in the past.

You can just make copies, even if something goes wrong, only the copy will be affected. Oh well, your game, your call.
