This is our third year buying 3 weaners and fattening them up. Previous years they have eaten like, well, pigs! Food gone quickly, eaten noisily etc. This year they were bought at the same age from the same breeder, are the same breed, are given the same amount of food (not an exessive amount). But they race over, eat a few mouthfulls and then head back off to root around and dig. They mainly sleep or dig, we have never had pigs that dug so much. Anyway the question is, are they just eating lots of grass etc, or should we worry they arent wolfing their food down? Many thanks in advance.
