If she is eggbound and it's been that long, she may need fast intervention to get through this. If you have the option of an avian vet, that may be the best thing. Alternatively, you can do a "search" (see above search function) for eggbound and get lots of advice on what to do. This includes placing her in a toasty warm but not too hot bath deep enough to cover that back end but not so deep as to overly alarm her. You can't leave her side during this 15-20 minutes and afterwards dry her well with warm fluffy towel and keep her warm and quiet and safe in a dark, comfortable place to slow egg production. With food and water nearby. She may need extra calcium (liquid) to push this baby out but it's a different calcium than the oyster shell. Read the threads on eggbound and see what you think. If she is eggbound, time is of the essence.
How old is she? How long has she been laying eggs? is she eating and drinking? How is her poop?
