I looked up red-eared turtle egg hatching times: 2 - 4 months. I have a plastic sorta laundry box over the site where the big mama turkle dug a hole in my fargin front yard and laid her eggs as we watched.
And I put a solid cement block on top of the inverted box. Thataway, creatchy-poos like possums, raccoons, bobcats, and assorted other egg-eaters cannot get to the clutch -- but when the babies come up outa the ground, they can crawl right through the square holes in the box.
I dunno what the mama turkle was thinking, but she laid her eggs a good 500 feet from the nearest pond or canal. When she got done laying the eggs, she was clearly exhausted -- trying to crawl down my driveway toward the pond down the road. I picked her up and carried her over to it and she happily crawled in.
I will do the same for her babies in 2 - 4 months.
