Sorry but there is not a n easy solution as often homemade takes times to make and it sounds like you are in a hurry.
The easiest is to make silos using corraplast (plastic cardboard). Or to use Texas rags and add the dowels, etc...Another option is tyvek windsocks, but it is easier to buy them at Knutsons for about $2 a piece IMO.
I do recomend matching the species to the field, meaning if Snows and ducks are using the field, then use the same, ir Honker sna ducks are using it, use that to match what they are used to.
If going the Honker route, get the good quality ones, if it is RG silos, or FBs, but good quality lasts and fools the honkers much better than lessor quality does.
