Get four eggs, and whenever the Daycare man has an egg, pick it up and deposit it.
You can hatch eggs while working up a backlog.
When you feel that your backlog is large enough, fill five slots with fresh eggs, and go to the infinite loop and put something to keep your trainer going forward, like some kind of clip, or a piece of folded paper under the circle pad.
ORAS is the best game to do this in, because the 2nd Daycare is in the same place as the infinite loop.
