I believe the exploding doesn't happen this soon/early. The eggs have to get good and nasty before you need to worry about them exploding.
1st is a clear blood ring. 2nd looks like a blood ring but not clear from this angle. 3rd looks good. 4th looks somewhat like a blood ring but also maybe not. Give them a few more days if you're unsure, as many have said, eggs only explode after they've rot some. These were just dead for 1-2 days at most (if they are indeed dead), nothing to worry about yet.
