Hey Rodger, I have to admit in all the years I have worked with and kept collareds I never kept growth charts. The only time I got concerned about any of them was if I got one who did not grow. If I observed one not eating well or physically just not getting any/ or much bigger as time went on. Then you relaize there is some sort of internal parasite problem most of the time.

If your lizards are eating , basking, shedding and and you have seen a steady difference in size since hatching then for your own records start now and keep track of weights and lengths if you want, never to late.

I suppose you could get a basic idea of normal growth, but all mine are so different, some much bigger ( like the aquaflames) even the girls are stouter then others. The yellowheads tend to be some what smaller framed/ shorter then some of my other collareds. The NM seem shorter and stubbier. I have a NM montane mountain adult female that stays hefty but looks no bigger than a juvey. Just all so different.

Sorry I could not be more scientific.... lol, but after many years ya just eyeball it and know.

Take care buddy!
