Our strategy for Poached Eggs level 1-12 is to destroy as much glass as possible. Aim the blue bird at a low arc and multiply him right before the structure to inflict maximum damage. If necessary, use the remaining blue bird to take out the last pig. The score in the video below is 57,490.
Note: The bottom horizontal floor and bottom middle pillar in the video below are ice. On some platforms, and in older versions of the app, the blocks are wood.
