If a wishbone breaks down the middle it can mean a few things. Some people interpret this is equal luck for those who broke it.
When the pulling of a chicken's wishbone breaks equally, it is commonly believed that both parties will have their wishes come true. This tradition stems from folklore where the person with the larger piece of the wishbone gets their wish.
that its more than just luck but love
As far as I can tell it's because you and someone else break it together and whoever breaks off the bigger piece gets to make a wish.
If the bone breaks into three pieces, such that neither person gets a piece of the junction, then neither person's wish will come true.
People believe drying the "wishbone" of a turkey, then having two people making "wishes" while pulling on the two sides, is lucky. When the wishbone breaks, the person holding the larger piece is supposed to have their wish come true.
