I've weighed both pigs today as I've almost had them a week.
Chunk (boar) is now 407 grams; he's gained 72 grams.
Oreo (sow) is now 645 grams; she's gained 64 grams.
While Oreo was out I felt her tummy. One one of her sides I can feel a ball/blob that doesnt seen fixed to the spot? Couldn't feel anything on the other side but she wasn't very happy with me touching her tum if I'm honest.
NOTE: I didn't dig my fingers into her sides, I applied hardly any pressure, I stroke my hamster with more force if that's anything to go by.
I also picked her up buy getting her to walk into her carrier (thought it'd be good practice for weighing and vet visits). I supported her whole body while lifting her and wrapped her loosely in a towel to keep her calm but after 5 mins she'd had enough, so I put her back into her carrier then into her cage. I was very careful.
Both are now stuffing their faces. Given them both a small piece of broccoli stem to munch on which they're both thrilled about. Considering that the veg I've been feeding them for the week have been low calcium, a treat like broccoli should be ok once a week?
Yes, it should be OK, specially at their own young age. How old are they now exactly? They may be putting on weight simply on a good diet.
At this stage you still have to be patient and wait.
