i really don't hunt scrapes because you never know when the deer is going to show up *caution don't get too close of that deer will never come there during season* if the scrape is near the open like a field then the deer will never visit the scrape untill sundown but if it is in the woods then the deer will come check it during deer daylight.i think a decoy will help motovate the deer to come out in the field because by seeing another deer in the field they will feel safer i would say a good distance would be 50 yards and out
