Last night, when I took the piggies out for floor time, I noticed Chip was limping. And this morning, he didn't come out for his salad! He always comes running when he hears the bag. he just laid there, even after I left. Well, earlier yesterday I took down the divider in the cage, because my mom was at work I watched them for about half an hour and they were fine. My mom thinks Rodney attacked Chip. I looked on his leg and there where no bite marks or blood. Does anyone know what could have happened or what I should do?
