So my horsfield tortoise has laid 3 eggs, and i was wondering if they looked healthy and fertile or not?

This one is 4 weeks on. It has a huge sir bubble at the top, and no visible blood vessels or anything, just the big dark region at the bottom.

This one 3 weeks

This one two and a half. Has a dark blob near the top
Thanks for any help!
