I witnessed a painted turtle laying eggs in my front yard last autumn, and then she buried them. Using crates that have holes on the sides for baby turtles to be able to crawl through, I have them covered with weights, to protect the area from other wildlife critters who might want to dig up the eggs to eat them. They are still there; they've never hatched. Is it possible they will still hatch this spring? How do I know if they have been fertilized? I still have them protected, so when they do they could crawl out; however in the meantime other critters cannot get in. Thank you!
