I would start by asking yourself, WHY was he in the other locations when he was
is it wind< was a certain wind direction going on when he was in "X" place?
is it food
was it a week day or weekend?
food, what food/crops are there, WHERE There, still standing were cut?
and so on
be a lot of guesses still, but could be more educated guesses if you can come up with answers that seem to match why he was where he was!
also, think about HOW you went into the stands, and did that possibly have any reason why he wa where he was, as jumping doe on way in or scent getting into a bedding area, could cause them to be in different places too!
