We integrate ours between five and eight weeks of age. At 12 weeks your chicks are going to look almost adult. We might integrate earlier if we didn't have cats, but younger than that they still look too much like wild baby birds, aka "prey." At 6 to 8 weeks they are big eniugh to be recognizeably chickens, and the cats have no interest..
Are you brooding in the house? We don't use shavings at all at that stage. Instead we line their brooder with puppy pee pads and change them daily. Easy peasy and no dust!
