I take a few eggs out of the frig, put them in a petri dish, and keep them at about 85 to 89 degrees. They hatch in about 6 days. They will hatch at room temperature too; it will just take a little longer. Also, I line the eggs up in a row. That way when they hatch I can lay a sliver of chow next to the whole row and not worry about getting it on top of any of the hatchlings or eggs. Whether you order eggs or worms, just make sure they include a cold pack or two when shipped! This heat is ridiculous!
