Looks like an Anole egg. It's hard to say whether or not it'll hatch since it's been moved and turned so much. For a general rule of thumb "don't turn over reptile eggs"
A good place for an Anole egg is just about everywhere. They drop them all over the place... The safest place is under a rock. Most of our successful hatches seem to happen from under a rock in the garden. The egg is only dug into the dirt enough to cover the bottom half of the egg and the rock usually has some sort of dent in it that allows it to rest there undisturbed...
Many of the eggs around here are also found in the window sills and just generally 'laying around' on the ground under shady plants etc...
