I found the bill color thing to be very accurate with Welsh Harlequins (out of 10, we only had one that was "borderline" in appearance, but still we were able to sex all of them). In my experience, it is much less accurate with Snowy Mallards and Silver Bantams (same genotype). I don't even do it with mine anymore because I don't think it is accurate enough to bother with when I am raising large numbers of ducklings, but you should get at least a few that you can make a good guess on. There tends to be a lot of others that their bills are too middle of the road to tell. I can't really say for Snowy Calls, but I have a bunch in the incubator right now so I might be able to in the several weeks.
