Hello. I have moved last year and for the first time, I have a lawn to put my piggies on. However, I am not sure if it’s ever had any chemicals on it (I’ve been here for 9 months and not put anything down). Also the grass is full of moss, clover and other weeds. I’d love to put my piggies out (in an appropriate run) but am also terrified in case they eat something they shouldn’t. I couldn’t bear to inadvertently harm or kill them. Can anyone advise me, please? Thank you
