I have a 14 week old Khaki Campbell duck named 'Hendrix'.. I have had Hendrix since he/she was 1 day old. I assumed at around the 8-10week mark Hendrix was a girl, I know Hendrix' parents and she is identical to Mum.. However! Now at 14 weeks Hendrix' 'quack' is dry and raspy and not really a 'quack'... so could Hendrix in fact be a he??? Hendrix is around 8 weeks in this pic, size and colour are pretty much the same now at 14 weeks.
