We have 2 Rouen Ducklings that are close to 9 weeks old. Not sure of their sex, although one seems to be making a raspier sound. We bought them from Tractor Supply. Our duck area is too small for the 6 that we have now. The 2 Rouens are on chick grower, lettuce treats, and are able to free range most evenings. We live in teller county, so if you would like these beautiful ducklings, please let us know. Thank you! Will be posting pictures.
