I have crested Rouens who are currently laying. I also have just feathered crested Rouen ducks - they are just about mature and should start laying later this year. I'm in Northern Illinois but am willing to deliver or meet you at a reasonable distance if you are interested in the young ducks. You can PM me or email.
I have crested and non crested pekin ducks running together in the same area! If you would like to see pics of them please check under archives. Or if you cannot find them, please pm me and I'll send you a link. We full time farm and I need to get back to picking for a market!
