Kira, I have two cats that like to hunt. I got chicks about one year ago. The cats were very interested when the chicks were small, but within a few weeks the chicks were old enough that three against one was too scary for the cats. I think that as long as you keep the cats away while the chicks are small you should be fine. Now the full grown hens are about the size of a cat, the cats like to see what the chickens are up to but are not a threat to them.
I'm always stunned when people post pics of 2 day old chicks with cats. I don't trust my cats that much. To them, a day old chick must look a lot like a half grown songbird. Came home to a small dead rat today, thanks kitties. Worry about hawks and raccoons.
