Boys quack, girls honk. I know. I've read that information many times! At about age 3 weeks, one of my beautiful ginormous Pekins started to honk. It surprised everyone, including her! I was so excited - one girl out of four ducks! Yeah!!! The honking slipped out more and more often. I didn't mind. I kept thinking she's going to be a momma duck one day... At about age 6 weeks, the OTHER ginormous Pekin duck made a honk noise. No!!! You're suppose to be a boy duck to be a daddy duck. It's kinda a requirement - boy duck meets girl duck, make baby ducks... It turned out to be a rather weird honking day. After that day, he/she didn't honk again that I heard. Now they both quack LOUDLY. Very seldom do I hear a honk. Actually, the sound they make is in between a quack and a honk, but not distinctly either one. The one day honker actually went through a period of his/her voice lowering/getting deeper. Now I can't tell whose who by noises anymore. Is this normal for Pekin ducks?? Both are very vocal. The one I thought was a girl is definitely more talkative to me. I have two Pekin ducks and two Khaki Campbells. They get along pretty well together. The bossy one is the Khaki Campbell (and she's like 1/3 the weight of my Pekin!) Edited to add this question - one Pekin has a tight, slightly pointed tail feather back end. The other Pekin has the tail feathers fanned out almost all of the time. Are either of these indications of the duck's gender? I know it's too soon to see the drake curl.
