I am upgrading my 4x4 blind to a 4x6 for more room. I am leaning towards going with the 48"x12" hinged window from DeerView. Part of me thinks that may be a little too big. What do y'all prefer in your 4x6? As an added note, the 6ft side is what is going to be facing the feeder.
I might going smaller size, 12x18. Not more than 24 wide. If using the 18 u could put two on the long side, if have two people in blind. The smaller the windows less for the animals to detect. Depending on distance to feeder 18" still gives a good field of view.
