Or you can just Thief/Covet them. I managed to chain Chanseys for a while and ended up with four Lucky Eggs. And like 18 Oval Stones lol.In DP, you have to catch a wild Chansey, and that Chansey will have a 5% chance of holding a Lucky Egg. Serebii has a pretty good description of exactly where to get Chansey and what levels it will appear at.
