My pair has lived together forever...Female 15 last march and male is 11. they have cohabited since the male was brought home. I have had them a few years got them from my old boss. So my question is while the female is doing her job is it OK to leave the male in the cage?

I usually let them roam around my room and leave the lid off so they can get to their water but the temp in my room is falling and I always put them in their cage for winter but with the eggs should i just get another set-up for him? I mean I am 99% sure I should I am just looking for a way out of the expense. It's day 56 today.
