The white poo (urates) is what's left over after they've saved their urine for a long time. It should normally be creamy consistency. If it gets hard and crumbly it means the tortoise is dehydrated. Tortoises don't always let out urates, only occasionally.
Tortoises are territorial. They want to live in their 'territory', a place where they know they're safe and there are no other tortoises to fight over. When you keep moving the tortoise around it never gets settled into its territory. Put it outside during the day and if it doesn't have a safe night time shelter, then it's ok to bring it in and place it in a cardboard box for the night, but back outside the following morning. It will soon come to realize that the outside portion of the tortoise's day is a safe territory.
Has your grass ever been treated with herbicides or pesticides? Does the tortoise poop? How often? Besides the urates, have you seen pee? What's the temperature outside? Is there shade? Sun? Shelter like bushes, etc.?
I'm sorry to say, but if this tortoise doesn't start eating once it settles into the outside territory, you're going to have to take it to a qualified vet.
