My ducks are 7 weeks old and still no idea if it is a girl or a boy. I am guessing being they are not quacking by now they are both boys? Moe at 6 weeks and then 7 weeks Pickles at 6 weeks and then 7 weeks SO hoping one of these are a girl. I have 2 cayugas that are. Being i read that you need 1 drake to every 3 ducks I am hoping one of these are a girl so I do not have to add to my flock.
