D'uccles experts needed! Are they roos or pullets?

Nice.
I was going to say both were likely roos. But kudos.

Honey may be a slow developing roo. Now a month later, I'm seeing some sex feathers that are distinct. I just don't know but I think it is a roo after all.

edited to add: This d'uccle is 5 months old, fyi.

what do you think?
