Is this a summer thing? They are all black. I saw the mother once out by my burn pile... i moved my straw into the garage instead of the garage addition with a dirt floor in it. I am hoping they wont go into the garage on cold concrete and do this... its right next to the chickens. I know that the chickens will kill the babies if they have a chance, and i dont think the adult is dumb enough. I am hoping that this will be the end of it. and its a garter snake variety( hubs loves the herps) and has assured me that they are not of the jaw- hinging variety and CANNOT eat chickens.
