if you get to her tomorrow and the hair will pull out in clumps i wouldn't eat it, just leave her where she lies. if she started bleeding within 10 yards and the hit looks at least decent she is probably dead pretty quick.
imo if i couldn't see blood very well and it is warm outside and i couldn't get help til the next day i wouldn't take any shots when it starts getting late, but thats just me.
if you made a good shot she is long since died and she probably wont be any good tomorrow or at least i would eat a deer that i left out over night if it is more than 40-50 degrees outside, again thats just me.
i would invest in a bow bug to help track animals at night. imo it would be a good investment if you can't see blood very well.
