My Ameraucana stopped laying 2 weeks ago or so, and she would go in the nest box but wouldn't lay anything. She hasn't been back in the box in a while, and was acting fine (eating, drinking, normal poo) but today I noticed a bunch of feathers missing, and they continue falling out when I pet her. She was fine all day, but when I closed the coop, she was just laying on the ground, not dust bathing. I took her inside and she's eating blueberries. Do they feel sick in a molt or is something else wrong?
