If your ham was a baby or very young when you got him you will see quite a big change in size over the first few weeks as they do grow quite a bit & fast!
Hybrid weight varies a lot from one to another, anything between around 50-75g is quite normal, they don't tend to become overweight if fed a good healthy diet & have plenty to keep them active & busy.
They do probably only eat about a heaped teaspoon a day but they should always have plenty of food available, enough to eat & some extra to hoard, never leave them without a fresh supply of food.
It's a good idea to weigh ham so you can tell they are maintaining a healthy weight once fully grown but the main purpose really is so you can quickly notice if there are any weight changes that might indicate a health problem.
