BKE sent me a message asking about using a natural ground blind so i thought i would give him my thoughts and then maybe ask some of you guys that use a natural blind to hunt turkeys what you do.
I feel that the best possible ground blind set up is using cedar trees. Whether you can get at the base of a large one and build up a little blind in front of you, or if you just cut down a bunch of cedar limbs and build a blind. Cedar trees/branches have a lot of cover on them and do a great job of blocking out light, making it easier for you to draw.
I would say the number one thing, is to have a GOOD BACKDROP. It will help break up your outline when drawing.
Also, with the decoys...if i were hunting a double bull i would probably have them a 5-7 yards, but when using a natural blind, i personally do not want the birds that close. I usually set my decoys at about 20.
Here is a couple pics of a setup where there wasnt a cedar tree and we just build a good backdrop and whatnot. Hope this helps!
