Ameraucanas, or more likely an Easter Egger, are often not prolific layers.
Can you post some pics of her, full body shot and a close up of her head and comb?
Glad to see she
did molt after reading this thread:

As long as she's eating/drinking/pooping and moving around OK,
there's not likely anything you can do. She is just is not back in lay after her molt.
Positive reinforcement won't have much effect on laying.
Too many treats could have a negative effect.
They need a balanced diet to produce, some need more than others.
