We want to start planting a perennial livestock pasture and wanted to free range our chickens on it as well. I was looking into orchardgrass, but another post on this site said that feeding this to your chickens can cause crop impactions. Do you think free range chickens will go too crazy on the orchardgrass? Should I just stick with timothy instead? Alfalfa is out, I'm using the pasture for silage and the rabbits cannot have the alfalfa.
