Hi there! We are new to ducks and recently had 15 Call Duck Eggs shipped to us. We candled on Day 7 and 3 of the 15 were infertile. By Day 14 2 of the eggs that had started to develop died, leaving us 10 eggs. All 10 eggs made it to lockdown, but sadly 2 of them didn't survive the hatch. So we have 8 little gorgeous baby Call Ducks. I am curious to know what colors they might turn out to be at maturity and was wondering if anyone could help me out with that. I assume that my 3 yellow ones will be White Calls, then I have one that is almost black on top, has a yellow chest, mixed colored beak and legs, 2 of them are a silvery color on top, yellow on the bottom and have mixed colored legs and beaks, and then 2 of them are brownish/grey with yellow striped throughout with dark beaks and legs. Also can anyone tell me how to sex the ducks?
