IMO, articles discussing improved food value of sprouts (compared to whole grain) even though they are focused on human nutrition ARE PERTINENT. Improved food value, regardless of the species that is eating the food is a good thing. As for the cost of sprouting for a BYF, aside from a little time, a little space, and a little water, there is no added cost. It takes me less than 5 minutes/day to provide fresh sprouted grains to my flock of 25+ birds every day during the winter.
