So I got 3 ducklings and their turning a week old today. Two welsh Harlequins and a Blue Swedish. I know it’s hard to tell early but I was wondering if anyone could all ready tell the sex...... I bill sexed the Welshies so I’m pretty sure there girls..... although one of the Welshies is a bit bigger, should I be worried? Anyways, any ideas on the BS? I have no clue if it’s a boy or a girl. Thanks.
