I hope not, but she is showing a few of the symptoms (lack of egg laying being the main one). It's confusing though because only her crop is swollen, not any part of her body. She has been "off" for an entire week, but has not gotten worse. If anything she's acting more like herself (being dominant, dirt bathing, going for treats) compared to last Friday. Her main issues are constantly full crop, not eating much food, and watery number twos. If it is indeed EYP, how long do you think she would go on like this until succumbing to the infection? Thank you for your input, I am always trying to learn more about raising chickens.I hate to say it, but it sounds like she may have egg peritonitis.
