As I said, I have never had a problem with my cats and chickens. I have six cats, three of them outside and known to hunt. They have caught mice, birds, etc. I have three inside. One who is a fat lazy butt, and two that again, have caugt a couple of mice in my house. I also have a small parrot in my house that gets outside of it's cage daily. While curious, the cats have never attacked the bird. He would bite their nose off if they did! I raise my chicks in the house. Now, they have a secure brooder, but one day I left the lid open and went in the room later to find my fat cat in the brooder with the chicks! There she was, just sitting in the corner of the brooder watching the chicks. The chicks were in the other corner, watching her! LOL. Every year my fat cat knows when I'm going to hatch chicks. She's there when I turn on the incubators and sleeps beside the incubator, she's there when the chicks hatch and sleeps on top of the brooder. She's just nosey and loves watching the little chickies. The other two cats are actually scared of them.
My outside cats don't see little chicks unless a hen hatched them, even then, they are in a pen. My larger chickens free range every day and my cats don't bother them one bit. Run from them in fact. Found a stray cat in a coop one day, poor thing was starving, but again, he just wanted out of the coop and couldn't find his way out. He was hot and panting and very scared. I helped him find his way out, but again, no damage done to the growing juveniles in that pen. I've never seen a cat attack a crow, so I doubt they will go after a chicken. Chickens are just to big for ordinary cats. I'm not talking bantams here. Now, if you have feral cats around your neighborhood, they may be hungry enough to try. But a cat that is being fed, I highly doubt it's more than curiousity.
