Not sure, as we usually have plenty of grass. The picture looks like what is offered up for rabbits, but they have teeth so could grind the chaff up smaller if needed.At my place, every summer there's very little forage for the hens to eat.
Would lucerne chaff be an adequate forage supplement? I believe lucerne is called alfalfa elsewhere.
As a hay, it has very twiggy stalks that might cause crop impaction. But as a chaff it might be ok
Any thoughts?
