Hey!! I want to find out if my call is a male or a female, i know she is too young (she is 27 days old).............but......i still want to try!!! She has greenish head (new) feathers, can a female have that?? She is VERY mixed you see that a Lot of drakes (including big ducks, not calls) mounted her mum, so she is probs a big mix up of duxs, her "main" dad was bibbed call that looks like this and her mom (i believe) looks like this (her mum i believe is a "grey" call) and these are her "green" feathers is this a male?? And....when do calls stop growing (not including juvenile molt) thanks for any help!!!
