We are getting our first chicks in a few weeks, and we have 8 barn cats. The little fellas will be in the house (basement) the first few weeks, and in a chicken tractor or their coop at all times until they are bigger, at which point I THINK my cats will not bother them. I mean, would most cats REALLy take on a big, mean chicken? I never even see my lazy beasts with anything but mice and shrews, occasioanlly a baby bunny. Course, I don't see many birds aorund eitehr, but maybe that is just intuition on the birds part?
