These girls are 7 months old. Digit is in the middle and I assume she is blue. The one that is mostly all white is Torpy and she has a smudge on her head as well as pale greyish with a hint of brown tail. The other girl is Charlie and she looks like a chocolate pied in this photo but in real life her darker feathers are more grey. I'm all confused about what they are, except Digit. Can anyone help me? This is a picture of them as ducklings Torpy is on the left, Digit is in the center with Charlie right behind her.
