The golden egg #2 is located on Mighty Hoax Level 5-19. You need to fully zoom out in order to see it on the far top right corner of the screen. It can be reached with the first yellow bird, and probably will take a couple of tries before you unlock it.
Below you will find the video that shows both the location (or how to find it) and the starred golden egg level walkthrough itself.
