I'll see about getting her to a vet tomorrow as I have school on Monday and won't have the time. I'm also still unsure about the supplements. I've been told i'm giving them to her wrong but I don't know what is right.All you need for a lay bin is play sand. Coco coir is too loose and isn’t able to hold any form. I honestly don’t know if she’ll continue laying no matter what you provide her at this point. As @kinyonga said, ” there will only be so many days that she will dig before the hormones change and she won't have the urge to lay.”
If she doesn’t get those eggs out one way or another, feeder choices and other husbandry won’t matter at all. Waiting until she’s in absolute distress will decrease her chances of surviving if she needs surgery to remove the eggs. I think giving her until Monday to lay on her own is reasonable (although I may be wrong and she may need sooner) and taking her to a vet ASAP if she doesn’t. It would also be essential to let the vet know all of her behaviors and actions in the past few days. If she is eggbound and not given surgery to remove the eggs, she will die and it will be painful for her. I don’t want to scare you, but this is how it is and it can be very serious.
