size of horsfield tortoises

Hi I have been given two three year old Horsefield tortoises by someone who was not able to look after them properly. I was shocked when I collected them as they are so tiny one is 2 inch and the other 2 3/4 long. I have an 8 year old male and he was much bigger than this when he was that age.

Are they too small due to their previous inadequate housing, light, diet and calcium intake?I am pleased to report they now have a a choice of facilities a viv for winter and until they get a bit bigger. The viv is necessary as the bigger one is trying to hibernate and it's too small and it's appetite not fantastic either so I can keep a close eye on them, make sure they are warm enough etc. I have also got indoor and outdoor enclosures when they are ready
I called at a pet shop today for some advice their tortoises had been kept in a viv for the last 4 years and were aged 3 and are massive compared to my 8 year old.

I am confused! is there anywhere that tells you what average sizes, weights they should be? And is it possible for them to grow to quick? or too slow?
Any Responses appreciated
