I'm thinking of turning my one large pen into a dry lot. It's close... only a few spots of grass and nibblys, but I want to totally eliminate all of it to help with parasite loads when I'm not rotational grazing. Send me your pics! What do you use for the ground? How often are you cleaning them? How did you get rid of the grass, did you just cover it with spent hay? What type of toys/platforms do you have for them?
