Our ducks are 6 weeks old and pretty much all have brown feathers. We're pretty sure we have 2 mallards, 2 fawn and white pekin looking ones, 3 khaki campbells, one other brown guy, and even the duckling that came totally black and we thought was a Cayuga now has a lot of brown on him. Will these colors change? We only have 2 quackers, and they quack LOUD... the rest are cheeping so we're thinking out of 10 ducklings, we only got two females. Is it too early to tell? here they are, they looked so different as ducklings and now they all just look the same... I'm new to ducks so I have never watched their feathers change... But we're ordering more ducklings to get some hens if in fact we have 8 males... Any insight from experienced duckers would be much appreciated!
