I'm in AZ. I keep heat on my turtles during the winter. Maintain them around 77°. They're southern painted turtles. The female produced eggs this year. She's young. 3 years old. She's able to do so because size and not age is most important for ability to breed. All of this I learned in college. So, I'm not following your logic on needing the cool winter temps to help with ovulation.
You must be lucky then. It’s pretty well proven across the board that in order to have a “successful” breeding season i cool down is needed. Doesn’t mean it’s 100 percent of the time but for a large majority this is the case
@State 48 Turtle & Tortoise From where is that supposedly well known? It doesn't match what I was taught, while in college, by a DVM (Doctor of Veterinary Medicine) and the rest of my instructors versed in animal husbandry, medicine, etc. If I was not taught correctly, and now am merely lucky, I would like to know where it's well known that brumation must occur for proper ovulation in turtles.
