Golden Egg #18 is located in Level 1-10: Break the patch of grass beneath the slingshot (the one on the side of the hill). The egg will swing down from the top of the screen. (→ see image)
Note, this is a two part video. The first part shows how to find the Golden Egg and the second is a walkthrough on how to pass the actual Golden Egg level.
