Hi---I just joined this forum, and need some advice! I have a beautiful Rhode Island Red hen that I raised since she was purchased as a tiny chick at the local feed store by my impulsive teenage daughter. She is now one of our pets. She roosts in her cage, and has a coop where she lays her daily egg. She has the run of our back yard. She will hop onto your lap and cluck. She is 1 1/2 yr. old. We have a cat, who lays in the sun on top of her cage, and they get along very well. We also have two dogs, and they have no problems with our chicken. Our new neighbors over the fence have a cat, and I have seen her in our yard, hissing at our cat. I am wondering, could a medium-sized domestic cat cause any harm to a large healthy chicken? If our pets get into the chicken's space too close, she will squawk and peck at the offender. Do cats usually attack chickens? Prior to this chicken coming to our house, I had zero experience with farm animals or chickens. Any help/advice would be appreciated!
