I am pretty sure my chicken has sour crop but I thought I'd ask and make sure. She has had liquid coming out of her mouth, sometimes it's clear and sometimes it's a light brownish color. I also noticed this morning that her crop is still very full and it's squishy. She's eating and pooping fine. Running around normally. Does this sound like sour crop, if so what do I do. If not then what does it sound like?
