Hey everyone im new to RES turtles. i have a yr old male hatchling named Pee Wee

, a 2 yr old RES male named olympus

and a 3 yr old Painted western female named scarlett

. my scarlett is cting crazy...shes very restless and constantly trying to get away from olympus. i did research and found out shes pregnant. i DO want to take care of the hatchlings and already have homes for them if she lays eggs. now my question is how should i build her nest? i dont want her to get sick bcuz of egg binding. and im VERY broke at the moment. i have less than a dollar to my name right now...how can i build her nest and what should i do to take care of her and the eggs? PLS HELP!! also i have sand and organic compost...i plan on turning my closet into a nest with boxes and stuff...how deep does it need to be and how warm and wet?
