Okay, brilliant? Maybe just very aware. But seriously it's amazing what comes preprogrammed in them!!! They've never seen an adult chicken but today I had them outside for their "fun and forage time". I was down in the grass with them and all of a sudden they quit their little chortling and we're all looking up. So I looked up and dag nab it if there wasn't a hawk circling overhead!! . Wow! How do they know to look up at that and be quiet?! I'm not very thrilled that the hawk saw them either! I never leave them unattended though and they are in a covered run. They are 2 weeks and 2 days old. They amaze me all the time with their antics too!
