Level 12

Can anyone help me with upper right square? Cannot figure out how to break chain to get spyglass piece.

You need to match the birds one by one so that they fly away. You can move birds into the block from the bottom - they can sit on the arrow key.

Then when the last bird is alone you can match him to free him so that you can move him.

Hint: If eggs are going to hatch in that block move a bird onto the egg so that they don't.
