There really isn't a well-defined second rut anywhere because the majority of the does are bred the first go-around. But, in areas with a skewed sex ratio, a higher percentage are not bred the first time. Does that miss out the first time come back in about a month later. So, just add a month on tot he regular 'rut'. But even then, since the initial breeding period is usually drawn out over a few weeks (some does come in earlier and some later depending on their physical and physiological age), a group of does that come in to estrous the second time will also be drawn out over time, just less noticeably since there are a fewer number.
