Will these work?

Made an attempt at my own sandhill decoys, think these will work?

If you are where they want to be, or where they are crossing into a field. Also if you are VERY well hidden, I would think you could kill them over those.

Sure they will work. Id throw for a half a dozen full bodies to mix in with it.

They look about like divebomb silhouettes so should be able to at least kill a couple with them.

I would be cognizant of the sheen from the sun... I'm sure the paint is still wet in your picture, but something to be mindful of.
