I have noticed this for the last few years here in West Virginia. I believe
it's corn dust or pollen they find aroound as it's the same color as the
pollen baskets on the bees I've noticed rolling around in the laying mash
and corn I give the chickens. I live in an area where a lot of people keep
beef cattle over the winter and feed corn.

pollen
