On pokemon Dimond, Pearl, and Platinum you can easily create free eggs of some of your favorite pokemon. Here i will take you step by step on making multipe pokemon eggs.
Step 1: You Need
To make eggs you need:
1) Pokemon Platinum, Pearl, Diamond
2) Nintendo DS or DSi
3) Access to the daycare cuple in solaceon town
4) Two pokemon that are in the same egg group or a ditto and a breedable pokemon

Step 2: Do It!
First, Get on to your pokemon 4th gen game. Then, go to Solaceon town. I would use fly if you are far away. look at the pictures to figure out where it is on the map. When you get there, be sure to have a bike on Y set if you want to make this easy. Get in front of the daycare like in the picture. Go inside ans you will see an elder. Go to the pc box beside her and get your pokemon. Make sure they are breedable. I am using two Lavitars. One Male, and one Female.
Step 3: Breed, Breed, Again
once you deposit your pokemon, you can gat a free pokatech upload thing! you will see that there is a man in the corner with glasses if you tell him its hard to keep track of your pokemon in the daycare (or something like that) he will give you the pokatech thing. Once youre done, go outside and switch your pokatech onto the daycare. you will see your two pokemon. get on your bike and bike against the line where the road ends on the right side. go north and south and tap your pokatech every once and awhile until you see an egg in the middle of the two pokemon.
Step 4: Free, Fresh, Eggs!
You can get the egg from the elder bald man in front of the daycare. say "yes" to his questions. Ta-da! you received an egg. This is a smart way to get your favorite pokemon cheaper beacuse you dont need to buy the pokeballs and you dont need to waste your time finding it.
Step 5: How to Hatch
To hatch the egg, all you need is your bike and usually less than 10mins. Just, as i asid before, bike around until you hatch your pokemon. the easiest way to hatch 5 pokemon eggs is that you get the eggs, bring your toughest pokemon and bike back and forth from solaceon to twinleaf town. Hope this helped you! This is my first instructable.
