So, one of our 4 hens is a Speckled Sussex named Nina. Nina is my 12 year ols sons hen ans he can do anything with her. He pets her and carries her around. I am also able to do just about anything with Nina. My husband on the otherhand, she attacks! He can't think of anything he could have done to upset her aside from moving her off of the nest last fall when she was broody and he wanted to collect eggs. She literally attacks his shoes and pant legs when he enters the coop enclosure. He often takes special treats to the hens and he is always kind to them. He can scoop up the others and pet them but for some reason Nina seems to hate him. What can we do to change her behavior?
