A few things:
- Fruit is not good and not needed. I would skip it entirely.
- Hay is not a good food for babies. Fresh young grass that is chopped into small pieces will serve your tortoise much better.
- Very difficult to maintain correct conditions in an enclosure with an open top. Closed chambers work much better. Like this: https://tortoiseforum.org/threads/new-stack-of-animal-plastics-closed-chambers.165626/
- If you must use something from the grocery store as a base, use endive or escarole, not romaine.
- Best to use as many things from this list as you can find or grow, and skip the grocery store altogether: https://tortoiseforum.org/threads/for-those-who-have-a-young-sulcata.76744/
- Pyramiding is caused by growth in conditions that are too dry. Not by food.
