Poached Eggs level 1-8 is the level where the Golden Egg #6 is found. You just need to keep tapping the treasure on the middle of the screen until the egg pops. If you are on a desktop (PC or MAC) you must click and hold the left mouse button over the chest and type in your keyboard the word open.
Below you will find the video that shows both the location (or how to find it) and the starred golden egg level walkthrough itself.
