Thank you, that is much more in line with their size and looks. Unfortunately, since the birth weight can range from about 40-120g, weights and sizes in youngsters can differ massively and that will carry on through their lives.
The crucial point is NOT where they are on the weight chart but that they are on a good normal grass hay based diet and have a good, enriched life because that is all that is needed to allow them to realise their their genetically determined optimal size and weight - whatever it is. Being on the smaller side for their age doesn't in any way mean a shorter life span or health issues. I've had enough dainty piggies living to 7-8 years old without ever being seriously ill in their whole life even though they were scraping around the bottom end of the adult weight range (700-900g). Your babies' weights are at the lower end for 8-9 weeks old but they are not dangerously low.
My Begw was just 210g (the weight of about a 3 weeks old) when she was surrendered as a no longer wanted baby boy who promptly turned out to be a baby girl and arrived here in a hurry to be bonded with my newly single husboar Dylan (who had to go through the mandatory quarantine with her because her need for companionship came before quarantining considerations at that young age). She is now 2 years old at the peak of her life, still only a handful at just about reaching 800g, but a nicely sturdy handful as you'd like to see at that age. But seeing that she still is my smallest ever adult, I had revise her aage upwards again to the stated 8 weeks.
As long as they are not losing weight and will continue to put on weight most weeks because the growth rate pattern shifts to spits and spurts, they are doing fine. In my own experience, it is less whether they are small or large for their lives but what kind of life you give them - and a perfectly normal diet and lifestyle is actually best because long term healthiest. I have and have had a number of rescue adoptees from true hellholes, but a surprising number (provided there wasn't a genetic issue beyond my control) has lived a normal or even longer life span); the piggies have often been among the longest lived of their rescue group.
Don't get fixated on weight and age; they look to me that are around 2 months old. What counts is that you give them a good and perfectly normal life without feeling like you need to throw the kitchen sink at them and hitting them in the head with meaning too well.
Piggies don't reach adulthood until ca. 15 months and can retain the ability to make up on lost growth due to neglect until they are about 2 years old, so that is a VERY long time to get to their individual healthy optimum weight and size - whether that is within the narrow band of 50% of 'average' piggies or the other perfectly healthy half that doesn't fit arbitrarily set human ideas of 'ideal'.
Thank you very much I got lucky! Thank you for your helpful advise! X
