Quoted By:
When I was MM'ing mine. I just had a Talonflame in the front of my party and I just kept going back and forth until one would hatch. Then I'd throw it in the box, come back out and grab an egg since one was always ready and repeat. Once you get going, you start hatching them at maybe one per minute, since by the time an egg in the 6th position moved to the 2nd, it only needed a little bit longer to hatch.
Does that make sense? You just keep putting the recently hatched one in the box and always keep a full party of 5 eggs and Talonflame, rather than hatching them by batches of 5.
