How old are my ducks?

[BigBlock]

I brought home a new pair of ducks a couple days ago and in the excitement I forgot to ask how old they are. Can anybody tell me roughly how old they are by looking? They are a magpie and white runner, both crested females.

Based on my memory of my runners, I would say between 1 and 2 weeks old.

Cute little pumpkins!
