Joe-
We took a rig of all cork and wood birds as well as hand made silos. The silos in the picture are floating on a V board. Can't find duck silos that we like so we make our own. We also use V boards to float commercial made geese silos that are readily available.
My partner and I's plastic company makes and sells the V boards that the silos go on as well as a land based model.
There are free patterns for the silos and more information on the V boards on our website.
