In your opinion, what is a normal and healthy weight gain for royals over a period of time please. I know fasting etc comes into play with some snakes but, for example, over 6 months or a year what would be classed as a healthy weight gain for a snake with no feeding problems?

I want to keep a proper record of feeds/poop/shed and weight for my new little ones and would like to know what to expect growth wise

Many thanks in advance, everyone here has been so patient and helpful so far xx
