Well... I just remembered earlier this year...
That when my male eastern wanted IT, he just sorta did IT with my female albino checkered. She wasn't cooled or anything.
So I'm thinking I may keep the females out to bulk them up over the winter, and only brumate the males. This would make me a little less uneasy about the whole thing, but the question is; would it work? Would cooling the males down and letting them go after the females be enough?
