I have 4, 8 week old Nankins. One roo. They all get along, don't chase or peck each other out of the way..they just run together. So, when I heard a noise that I hadn't heard come from my Nankins before, I look to see the roo on top of one of the little girls..isn't this a bit too early for that guy to be feeling his..ah hem..oats?? He hasn't even crowed yet! Boy, was that little gal surprised!
