We had 10 hens ane 2 cats. One of our cats, Willow, wanted to be a chicken. She was always finding ways to sneak into the coop. We would look out the window and see the chickens in their run, and there amidst the chickens was guess who. She just wanted to be one of them, and as long as she behaved, she was accepted. If not, they chased her away. She even went into the nesting boxes on occasions. Willow's sister Hazel wanted nothing to do with chickens.
