I really think that the University of KY resource is very useful when deciding what to feed and what not to feed as far as anti nutrients. And they give the reasoning and behind it, stating the results of studies on the subject.
I most certainly like the idea of sprouting seeds much better than ff for what it accomplishes. And, if you think about it, in a wild situation seeds that chickens would come across would most likely already have begun to sprout. At the very least the seed coat would have begun to deteriorate and soften some after being on the ground in the weather - which is the idea of soaking seeds and grains before eating them in the first place. There is a whole different enzyme profile available for digestion because of that process.
I've watched wild birds meticulously work at cracking open a seed or nut to eat the interior while leaving the seed coat. I've seen my chickens do the same thing. That's exactly what they do with sprouts (not fodder, sprouts).
Even when you think about how mice and some other rodents interact with seeds it makes sense. They gather them and store them, often in a dark, damp place underground that would accomplish the breakdown of the seed coat over time.
