They need a humid enclosure, not a wet one. Access to water to self soak in, yes. Redfoots are prone to a fungus called shell rot so you don't want them in a wet enclosure. Im sure living where you are the humidity is high. What is the average daily humidity level where you are?
Is that good?If they live outside your humidity might be fine as-is.
here in Florida the humidity is regularly over 70%.
