Just a quick question....my chickens seem to love grass and eat as much of it as they can. They are confined to a run and the grass has long since gone from under them, but occasionaly they will go out by the gate where theres grass and will eat it up. I think they know what is good for them and not, but is it possible for them too eat too much since grass is considerly tougher than other greens and would take longer to digest. Should i cut keep them away from it, or do other peaples chickens do the same?????
