looks like out of the six ducks I have 2 are going to end up being drakes. I have 3 rouens that are a few weeks old, 1 is has started to quack more so Im pretty sure its a female. The other two I think one is a drake, it still has a very quiet peep to it, the last one will quack when chased, so might be a female. I ordered 3 Pekin from Cackle and they are in the brooder, I bought 2 hens and a drake, so they are sexed. Is 2 drakes too many for 4 hens?
