I have a seven week old chick she is standing hunched she’s very lethargic and weak. She doesn’t have pasty butt, but I have not seen her go since I separated her the day before yesterday, she’s had water, codified, electrolytes probiotics she recently just spit up some brownish colored fluid when I was massaging her crop I thought at first she was impacted, but I think it’s sour crop because it’s more squishy and bloated. I just had another chick with the same thing, but she snapped out of it rather quickly have you seen this color fluid before?
