We're thinking of getting another tortoise to add to our family, possibly a baby golden greek tortoise. In October 2017, we received Spike, a baby ibera greek tortoise, as our first pet together! He was bought from Tortoise Supply when he was (roughly) 2 months old, and so far...
Lucky tortoise! My Greek, Spike, would be jealous of the weed abundance! We are trying to grow our own in pots and boy, is it difficult. We end up going on foraging runs for Spike and collecting weeds in our neighborhood.
Here is the little nugget chomping away:
I don't know what tortoise you have, but I think most tortoises' diets include broadleaf weeds like what you have in the 3rd and 4th photos. They are good for tort health; it's food they would find in the wild.
My greek is growing up on weeds and he seems quite healthy:
The weight gain seems normal also. My greek tortoise gained an average of 7-10 grams each month from when he was 6 months old. His weight gain changed drastically when he reached 12 months old, jumping from 14 gram gain to 31 gram gain. He's now 242 grams at 19 months old.
