The Pokemon day care for Pokemon Leafgreen/Firered is on island 4. You have to beat the elite 4 and get the machine on island 1 working to go there.

First take your starter pokemon and a ditto to the day care center on four island and wait a while. If you go back the man will have moved if there is an egg.

As long as they are of a different gender, they can be breed. This is true to most (or all) of the non-lengendary Pokemon with genders.
You go to cerulean city. Then you go down to the little plant and use cut, and after that you go down to a row of ledges and there you are at the day care center. Also you can find a daycare on four island.
the day care center in Pokemon white is at route 3 west of striaton city
Most Pokemon will breed with ditto. You might need to catch another one because they probably don't like each other. Only legendaries and genderless Pokemon won't breed with ditto.
