What dictates how far the nearest decoy is from the hide?

Or is it best to always stick to the same spacing regardless of conditions?

It?s not so much where your nearest decoy is placed, rather, where you create your killing area.

I usually try to make this no more than 25 yards from my hide, at which range my chosen choke/cartridge combination of 1/4 and 30 gm sixes has the optimum chance of success.

Sometimes the nearest decoy is only a few paces from the hide, and at others it could be more than 30 yards away, depending on the wind, but the killing area will always be at a constant range.
