Ken has sprouted grain for animal feed for decades. Sprouting adds nutrition to grain, and is more digestible.
Currently he soaks grain overnight and pours into screens he made.
Then he puts the screens in a rack he got secondhand.
He fills the rack. He waters the sprouts as needed
If the weather is dry and windy or cold, he covers the rack with plastic
Here is some sprouted grain ready to feed out to the animals
