I have a 3 year old chicken and I've noticed these two days that her crop feels empty. She's been eating not a lot but she's eating and drinking water too and also when she lays an egg it's been breaking and she's been pooping but really small pieces and sometimes watery with white. Does anyone know what could be wrong with her? Also any remedies I could do and give to her? Btw she's the only chicken we have. Thanks!
