No save just before you take the egg run around like mad hatch it check if it has the desired outcome if It doesn't soft reset would recommend grabbing something with flamebody or magma armor
You cannot save after receiving the egg otherwise is is set in stone or you go into online play and ask nicely if someone will give you one
Are you on? I can do a couple trades real quick, anything is fine I every single pokemon possible filled in my dex so even rattata would be fine it is most likely to be released
