I see light green substance on the white fletching. Gut shot? That was my first thought from your initial description.
Lots of Intel from that. What he could and could not see. Entrance in and exit out. He never spooked just walked down hill there is a scent branch out infront of blind but no scrape ,time was just before 10a.m. Oh, and how well I can open and close windows when they are near.
Agree with Cantexion. Looks to be back too far like guts. Will often wipe the blood off the arrow. What does it smell like? Hoping you had a nasty big cut expandable on the end. More time needed, don't want to bump him out of his first bed.
