She looks fine & healthy to me. Russian hybrid weight can vary an awful lot, anything from about 50g even up to 80g, as long as you feed a good quality food, don't give too many fatty treats & your ham is active with an appropriate size wheel (20cm) then it is unlikely that she would become overweight, hams don't tend to overeat & will just hoard excess food.
It's a good idea to weigh your ham as part of a regular health check all the same, that way you can spot any changes in weight that could be a sign of a health problem. It's best to get them to climb into something like a large mug or little box then pop them on the scales in that.
