I would say you dont have to worry much. Last year my dad and I had been working 3 birds, I finally got them in range and my dad hit one with an arrow. I took off out of the blind chasing it after it started flying and found it shortly after, this was on a friday morning. Two days later, on sunday, we went to the same spot and set the same exact setup up only 30 yards from the previous spot (This is a pretty open field) and I was able to get the other two back in and I shot one more. We did make a point to leave that spot alone friday afternoon and evening and all day saturday though. There is a chance they may be a little spooky but the bird I shot was at least 4 years old and he still came to that spot again. Good luck on getting another!!
