Don't I Feel Stupid!

Well, Saturday, we got home and were doing the usual nose count. Yep, nine Rouen ducks. Wait, hadn't I decided we had NINE hens? Yes, yes I had. Then why are over 1/2 of them suddenly sprouting green head feathers? Um, those are males. Yes, I made a mistake. I honestly thought they'd all already put on their young adult feathers. Read, sex-distinguishing feathers. ARRGH. There is only ONE that I'm reasonably sure is female. Oh boy, oh boy. Duck a la'range.....nummy!
