One of the guys I hunt with has 4 dozen homemade silo's, and they work O.K., but we've had our best luck when we mix in a dozen Northwind's (that's all we have right now, more would probablly be even better).
The silo's help draw the flocks attention and are low cost, but the 3-D and movement of the windsocks really seems to pull them in.
