I'm really hoping someone can help. One of my baby piggies (just over two weeks old) seems to have some kind of problem. He (I think its a boy?) squats as if he needs to poop but then squeaks quite loudly and gives up. He's been doing this on and off for just over a day I would say. He's always been smaller than the other baby, but seems to be eating ok. I'm really worried that something is wrong - does anyone have any ideas?
