What a nice great big habitat. If your turtles are rewarding you with that many eggs, you must be doing some things right.
Do you have any predation problems with the wide open space? Raccoons or such?
Also, have you had any trouble with keeping 1 year olds in the same vicinity as a full grown adult. At one, it seems like they would still be in 'food item' range.
Cheers and thanks for sharing.
I don't think I have any problems with predation. I honestly can't keep track of all the babies in the pen. There's 15 of them and I usually see 5 out at the same time. They each look a little different so I know I'm not seeing the same 5 all the time. The pen is too big to even find all the adults at one time. My dogs in the kennel next to the pen seem to deter opossums and racoons. My biggest worry is owls, but I've done all I can to provide as many hiding places as possible. I look at it as being a lot safer than the real wild for the babies.
The adults don't bother the babies at all. They're big enough to where they can't be hurt by the adults. I have 10 from last year that are still a bit small, so I'll keep them inside for another month or two, which is about the time the new eggs will start hatching.
