I had a broody hen last spring. She sat on 12 eggs and hatched out 10. I originally had her in a trio, but when she went broody, she attacked her friends. I separated them and she raised the chicks alone. When they grew up, I tried to put her back, but she didn't want anything to do with her mate. She was only happy if she was with her children, so I left her with her daughters. I put another male with them, but after a while, they attacked him. She seemed to teach them to hate males! They're with a tougher male now though.
Here she is when her chicks hatched.
