Do they actually hatch? I was just assuming they'd bring your eggs to the point of hatching but you still had to put them in your party to finish it off.
Did anyone else not realise this was a thing?
If you develop Isle Avue, you can use it to hatch out eggs! If you're hunting for shinies this certainly might help a little bit even though you've gotta wait quite a while to hatch out most of your eggs. It's just a nice little extra piece of help you might have wanted.
Do you use it?
