I never cool any of mine down intentionally at all.
That does mean I need to keep an eye on the females and palpate if I think they might be developing though.
One more thing worth mentioning purely in case you haven't heard - female deserts do not produce viable clutches so you may struggle to sell any you produce.
When you say keep an eye on the females how can u tell if they are developing follicles? And yes I've heard this but I have some family that just wants pets so I do have a market for these offspring.
