Also, Buff Orphingtons are known as a breed that will go broody. I have two that are members of my original flock and they go broody every summer. I have to toss them off the nest and collect eggs.
As far as roosters go, I learned from my first one. He was handled as a chick and was mean! He flogged me once and shortly after than, a predator go him. My other three roosters have all been great. I took a hands off approach with them and we get along fine. They move away from me and I don't do things to upset the hens with them around. I had a polish that was fine. He disappeared, but I had two of his chicks that were white leghorn crosses. Both of them were fine. One of them disappeared, but the other has a son that is part polish/leghorn cross and brahma. He's HUGE, but very calm and respectful. If you do let your hen hatch out some eggs, be aware that a large number of them will be cockerels, so have a plan to deal with them, otherwise you really will have too many roosters!
