That is all she wants to do now. I have had to throw away a couple of eggs already. Thank you so much for your time. They don't differentiate between good things to chew and those that might be dangerous. If you want to keep her fully flighted, it's your responsibility to monitor what she can get into.
Egg laying, with hens, goes hand in hand with paper shredding.
Generally, it's best just to let her have her eggs and set them until she abandons them. This will take about 4 weeks. Even while she's sitting on her eggs, she will continue to chew paper. You may want to offer things that she's allowed to shred rather than just letting her pick what she wants.
