Welcome to BYC. Glad you decided to join our flock. I'm a chicken person and don't know much about ducks (although I've had a few), but I have to admit that ducklings are the ultimate in cute. Definitely post on the duck link that Kelsie2290 left you with and take advantage of our duck experts there. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your Rouens.
