Has anyone got any tips on bulking up a piggy. Gus is about 6-7 months old but he still weighs under 700g. e fluctuates between 600 and 660 at the moment, the stress of travelling up the country for xmas caused him to lose a few grams I think but he's since gained them back. He's always been small, when I got him he was only slightly bigger than a large hamster and that was in October. My other pig Jack is 1kg and they both get exactly the same amount of food. Jack can't be stealing Gus's because they stopped getting on and I separated them. The only difference I can think of is pellets. I changed from pets@home nuggets to supa burgess pellets in December and it took me forever to get Gus to eat them and he possibly doesn't eat as many of them now as he used to. I would really like to get him up to a more robust weght.
