Hi Folks...Just read a good piece in my chicken book. Pull up clumps of grass roots and all. Of course no chemicals on it. Put them in the brooder with your chicks. They will nibble small bits of the grass and peck the dirt (chick size grit). But the main benefit is that if you are going to let your chickens range this will expose them to what the will find on the ground. It will help them build natural immunity. Cut grass is not good because them can try to swallow the whole thing and it get stuck. Youcan also use clumps of weeds if you know what they are. Chick weed is a good one. Magppie
