For those that are sprouting grains.... The term is malting. You are turning the grains in to mostly sugar. Weather that's a good thing for chickens I don't know. Anyway, if you do malting wrong it can be poisonous. Soaking should be less than 6 hours at a time an when they are good an saturated they need to be spread out pretty thin to let the air get to them. They then need steered up several times a day.
