This morning I went out to feed and when I tell my 3 "little" piggies (potbellies) Goodmorning they usually run out to greet me. This morning 2/3 did, my Porkchop stayed in his hut and the other 2 came out like normal rushing to the feed bowls. It is raining but not cold. I thought maybe he didn't want to come out in the rain so I took his bowl to him. He greeted me with some oinks, sniffed at the bowl and continued to paw at the hay like he was making a bed, uninterested in the food. Last night when I fed he was acting normal. The only thing I noticed about his apprearance was that his eyes were very runny/watery, I didn't notice a color in it, looked clear but under his eyes were wet all down his cheeks as if he'd been crying all night. Could there be something wrong with him?
