I find it odd that your snake has not had the rest yet. I hate to say it bt it's probably not a good sign.... Many times when this happens the litter is no good... I hope thats not the case but a snake should honestly begin laying and not stop until it is done with. Just like egg layers, normally they start having them and they dot stop until the process is finished. A lot of times I have found that when females do not lay properly and it's over the course of hours or days, you end up with bad eggs or babies. It's a part of our hobby... So don't be too upset if it does happen.
