They lived in the pig pen, but they could easily hop out through the fence if they wanted to. But they spent most of their time there. Smart, because she has alot of dogs that'd probably eat them; but they could easily hop onto the barn walls/etc to safety..
There are too many predators out here as is, to leave them out strictly speaking. I plan on building a pen that has a covered outdoor run eventually. Hawks; coyotes, the like. They are safe in the stall for now..
