I’m still new to Rouen's and am trying to figure out the genders to mine as well. I definitely could be wrong, but I think you may have all drakes! Hens will typically have more prominent coloring on their back feathers and brown/dark orange bills. They all also seem to have shorter and thicker necks which lean towards male. Excited to see your update!
