apple, teeth, diamond
It is supposed to represent the "Tree of Life" otherwise known as "The Tree of Knowledge of Good and Evil". It is found in the book of Genesis chapter 2 verse 9 and is meant to represent the freedom of choice. I must say that this movie randomly threw in biblical references without explanation and really should be taken purely for entertainment value.
I think it's supposed to represent Minny, Aibileen, and Skeeter. Minny would be the bird with the turned head, if you read the book, you'll understand this is just the way Minny is, and Aibileen would be the one beside her, but looking straight ahead as if she's staring her fate in the face. Skeeter would be the bird off to the right side to say she's separated from Minny and Aibileen because of her race, but she is also looking ahead just like "Aibileen." I don't know if this is how it's supposed to be seen, but it's just my guess on what/who its supposed to represent.
