Chandler And Becks's Smallest Baby

One of Chandler and Beck's babies ( who's now their smallest one ) was born with a black beak. However as it's growing older, you can see that the beak is slowly changing color to the customary orange. Once the baby is about six weeks, depending on the final color of the beak and the coloration of it's feathers, we'll be able to tell if it's male or female.

The baby is the one in the middle.
