RE: does it matter when you set up a blind?
To me NO
I have set-up the day before or during that morning. Neither has bothered the birds at all. I have set-up on sides of fields directly inthe woods or smack int he middle of a field.
I like to palce my blind using natural vegatation such as low hanging freen limbs or cedar trees and during the morning i always look for a western edge as it keeps you inthe shadows longer. Late day I move to an eastern facing. I do not brush my blinds in at all. To me turkeys pay no attention to them if you use the surrounding vegetation to blend in with. I sit as far back in the blind as I can and rarely wear a fasce mask. I keep my windows openings just big enough to poke a gun barrel out of. Whne I do poke a gun out to take a shot I poke straight at the bird in a slow methodical movement. I have never spooked a bird I was going to shoot at so far.
When blind sitting I always use decoys and the decoys are no more than 10 yards in front of my blind. That keeps me safe from someone sneaking up behind me. For someone coming straight on my blind will stick out like a sore thumb and another reason I do not brush it in. The above are full enclosed blinds.
I have also used a flat panel rag blind with great success. In thos blinds I use a camoed steel beach chair that places me right on the ground. Again I can place this under low limbs and I will brush this in a bit. Decoy placement is not directly in front of me but to my left as I am a right hand shooter.
In this type set-up I ahve hand Jakes and Hens come in and you would be surprised on how much movement you can get away with. I practive picking my gun up and then putting it down. Done slowly while watching the mannerisms of the bird you can mount the gun easily. Is a great learning tool.
Hope this helps
