I always refer to him as a boy, but lately he really doesnt quack at all and when he does its very low and raspy not as loud as when he was a baby.
Drakes don't quack-they do the low, raspy noises. All my girls quack and honk and chat constantly-my drake only pipes in once in awhile with his whispery low tones. It helps me pick him out of the group since he doesn't have his sex feather, yet.
