You have to leave 2 compatible Pokemon in the daycare. If they really like eachother, then they will have an egg. Ditto can have eggs with any Pokemon (busy guy).
to get eggs drop off two compatible Pokemon at the day care center and after a while(3 days) there will be an egg at the day care center.
