I have a chicken, about 8-9 weeks old, that has been outside for about a week now. She wasn't leaving the coop yesterday and acting pretty lethargic so I brought her into the garage with the heat lamp. I checked her breastbone and it is pretty prominent, her crop is squishy, her vent is clear, no pasty butt, she won't really eat or drink, and she is "pooping" a white liquid, no firm stool. So, from what I have read she either has sour crop or an impacted crop... or maybe something i have missed? I was wondering what I can do to help her, if I can help her. Any advice would be so appreciated. We are fairly new to this.
