French guy need help

I use a kitchen scale but its right, i don't weigh them at the same time.sometimes after bath, sometimes morning...
the first arrived the 20 of june. she was weighing 57 g. since this day, one week she weight 61g, an other 55g or 63...
So during 4 months her weigh didn't really change.

I don't understand why. It's the same for my three tortoises. They all eat weeds and grass, some lettuce, komodo pellets..

O just went back and re-read all your other posts and I don’t see any major red flags... keep in mind, I’m no expert.. I would advise that you weigh your tortoises the same day every week after a good soak and poo. One poo can change 3 grams and that’s all you really need to see to know everything is ok.. others can give you much better and detailed advice but I do wish you luck!

I really hope it is not Hatchling failure Syndrome Guillaume. That is how I lost my first Star.
Is their plastron soft? You can start giving them carrot soaks. With baby carrot food and luke warm water.

I don't think. They all eat a lot and are active all day. Just don't grow.
They are still very young, maybe it's normal. Let's see in one or two months.
