Hatch the bad egg.
Yes but don't let it!
Just walk, walk and walk again 'til the egg hatch.
You will need to walk/run/bike a certain number of steps to hatch the egg.
You walk around until it hatches you have to have it on your party to do it to. Then it will tell you that it has hatched
1. it will never hatch 2. if it did your game would really be screwy!(its one virsion of missingno.)
You need to run around like mad for 30 minutes!(in the game)
you don't get a charmander in Pokemon sapphire unless you trade it if so 3000-5000 steps so have fun
i got one from using the gameshark too many times on my sapphire version it was in my PC box ive tries to hatch it and it doesnt hatch
It depends on how many steps you take I think like they did in sapphire and ruby.
If you can hatch a regular egg in there then you can hatch an ostrich egg.
* Can you make an unfertilized egg hatch? No
