I read that at hatch, WH's are usually autosexing - males born with dark bills, females born with light. They then switch as they reach adult hood - males mature to light bills, females mature to dark bills. So, at hatch I thought I might have a drake and two hens. I still THINK that I have one drake and two hens from plumage, but the bill color never changed. Since these are my first WH ducklings, I thought I'd post a pic and see what others thought. SORRY THE PICTURES ARE POOR QUALITY. I took them with my camera phone because my actual camera broke several weeks back and I haven't gotten around to replacing it yet. The 'hens' (light bills) have more beige coloring on the shoulder area, but the camera just whites it out. It's actually quite plentiful. The 'drake' (darker bill and plumage) seems to be getting a darker head, and generally has much darker plumage over the entire body. These guys are 6 weeks old, they'll be 7 weeks this coming Monday (7/12).
