Hello all I am new to BYC. I have lurked on the site many times, since this is the place I have found many of my questions answered. I do have a question about one of my buff ducks I have two buff ducks one I know is a female (older and laying eggs), I can't decide on the gender of the 2nd buff. At what age does a drake start to get a darker head? My duck Dot is only 10 weeks old, and I was convinced it was a she. I noticed that it seems "her" head is getting darker starting at the bill. I would really love Dot to be a drake. Here is a picture of "her". if anyone can help I would really appreciate it.
