I live in Florida and have two scovy's that are 4 months old. Though Florida normally has good warm weather it's gonna be cold for a few days (37 degrees is the coldest so far) I'm worried about them being in this cold of weather. I'm new to scovy's is it ok for them to be out in 30 degree weather? They have a little hutch that's made from chicken wire with a tarp over one side of it for protection from wind and rain. Do I need to put them in a crate and bring them in at night?
