We've had them for 10 weeks so far and they should have been about 1-2 weeks old when we got them. the brown one should have been a bit older than the white duckling. This is how they used to be And this is how they look today They are trhe cutest ducklings ever and love to cuddle . I think that they must be duck (chocolate barred) and drake (white) from I've read here so far but I still doubt it some times. The brown duckling is more "elegant" in the way it eats, walks while the white one is more clumsy and still waddles. Also his legs seem to be taller and still growing than those of the brown one.
