The grains were milled already. Although, we also experimented with sprouting wheat and barley for chicken fodder as well. It worked really well too. We sprouted the grain in our greenhouse for the birds. But it was a lot of work as we had to keep the greenhouse fire going to sprout the volume of grain we needed for the birds. So we abandoned the idea. But if push came to shove, it would work well too! I did not make any calculations, but I suspect sprouted grain would result in even more feed savings, but it is also a lot more work too.
