I know a lot of redfoot owners keep their torts in a variety of climate zones but I was just curious at what age or size you leave your tortoises outside? Especially for overnight. Obviously predator proofing, temperatures, and humidity play a role. My Rosie is 2 years old and currently she resides mostly indoors in her 6ft x 4ft enclosure. I do take her outside in the Carolina sun but have yet to build an outdoor pen since my only backyard space has two large tort-eyeing dogs just a fence away.
