I just got 2 buff orpintons and a barred rock. Can I put them on the lawn with a screen around them. I am worried about the eating of the grass getting stuck in the crop. I have some plastic chciken fencing left over i used to put over the metal fencing in the adults run so they would stop eating my pumpkin plants. I would put 4 sticks in the ground and wrap the plastic around it for a little outside run for the chicks in the yard.
