The last couple of weeks some I have talked to have seen bucks really trailing some does around....I guess some of the last few to come back into estrous....So I'd say some doe estrous might actually work and sure couldn't hurt...As for rattling I personally would not....I'd say most bucks are worn down from the rut and wintering and not looking for a fight....On the other hand they may come to see if they could sneek away with whatever they are fighting over...I think it would just cause suspicion on the bucks part...
