Are my Hogs underweight?

[Tsubaki]

Maybe the non feeding and colder climate (They do notice even if you keep them warm enough) got him to brumate. When taken out of it could take them a while to start eating again, raising temp slightly helps usually. A year and a half is early for sexual maturing but definetly not unheard of or odd, could be a factor. I bought a hog that was still in the fridge when I picked him up, took almost a month before he became active. Another 2 weeks before actually foraging and eating. I can drop it in and he'll eat it at some point. Sometimes takes up to a whole day but eventually it's gone, just have to put it somewhere I know he passes by. Not all hogs like to be teased with food, some just need to be near it long enough. There's still a bunch of things to try, don't worry too much.
