I have a Rouen duckling that’s 4 weeks old and we’ve been trying to sex it, but we’re not going to try and vent sex them because we don’t want to risk hurting them. At first I thought they might be a male because of how yellow their bill is turning. Since adult male Rouens have the yellow bill...
I have these 3 Rouens that are at least 10 weeks. Can’t see any green heads or tail curls. Just checking to see what you all think?
First pic has always had a darker bill.
