I got the egg up to the third right flipper as the screen was scrolling up. Since I couldn't particularly get anywhere until it had scrolled up more, I kept the flipper depressed to hold the egg and wait. Upon release, the egg was stuck on the edge.
The new 0.0.2 update fixes held eggs freezing, and has a speculative fix for eggs getting stuck between objects and the top border (I saw it once again pre-fix, but couldn't find a way to reproduce).
