Yes, she stopped laying. She stopped eating also because last night her crop was empty and slightly squishy. Do you think she could have sour crop?
I think she's all in =)
I don't think she has sour crop, if it was squishy then she's been drinking. She's probably still getting some food, but if your concerned about it you could offer her some food near her nest. Do you intend to let her have some eggs? And if so do you have a place where her and any chicks might be secure where she can have access to feed and water for whenever she hops off the nest?
Or do you want to stop her being broody under there?
Do you need fertile eggs perhaps or not wanting to hatch more chicks? =)
