Because the difference between male and female is difficult to distinguish in some species like, Chiloe Widgeon, Bahama Pintail and others where the male and female are so alike it is recommended that you ring your ducklings as soon as they are in full feathers or at about 25 to 30 days old.
As to how this is correctly done will be explained in the digital below.
