General Healthy weights?

[tiny_hooves]

I finally scrounged up a kitchen scale, and while it may not currently be the most accurate one until we get a digital scale, it's the best approximation we can get for now.

Our boy has been taken to the vet (neutering consultation) and she told us he was around 3-4 months old. We haven't taken the girl to the vet as of yet, but they're almost the same size so I am off-handedly assuming she's the same age until the vet can see her and give me a better approximate age.
The boy came in at approx. 380 grams, and the girl is approx. 400 grams.

Should I be concerned? I checked through the other weight threads and keep seeing piggies that are at least a pound or just a little less then a pound at around this age. Or could the girl be overweight? They're both given pellet and fresh veggies and greens daily, and both have access to fresh hay at all times. Both are given floor time (separately) and run around a lot and play during this time so they get exercise. Am I doing something wrong, or are they just small pigs?

For GP's between 12 - 16 weeks, a good average for females would be around 650gms and for males around 750gms.

400gms is around the average weight of a 7 week old.

Just like with humans, body shapes, genetics, growth & metabolism can differ a lot. I have a 2 year old quite long female who only weighs a little over 700 grams, and is really really tiny for her length but completely healthy. The other one is unusually short, 1200 grams & "looks" overweight. What you should focus on is a healthy weight curve just like with children and not only the weight, and make sure they do gain weight as they grow & don't show any signs of an illness or lethargy. It's almost impossible to guess their age based only on weight.
