Out of curiosity how many DPO were they laid? I had a female lay over a week later than expected and they did pip a few days earlier than usual. Perhaps the reverse can happen if they were laI'd early. Also how dented were the eggs? By the time they're all sunken in it seems like they take up all of the space but like mentioned if they were fully inflated it would be probably around 2/3 snake. Definitely leave them alone to come out on their own. I'll be curious to know their weights once they're out. I've ways read to keep humidity at almost 99% and (knock on wood) haven't lost a clutch so maybe get that up higher for your next clutch and see if you have similar issues although humidity issues are usually obvious by egg condition. Good luck!
