Hi @FlyingNunFarm ! Now worries, and a great question. I'm updating the thread I started for our sick chick last year with the details I never recorded. I guess I was grieving and by the time I worked through it I had forgotten to write things down.@HoopyFrood not to dredge up the past and painful memories but you didn’t mention if your chick was pooping. From the details you’ve given I would say impacted crop. Impacted isn’t necessarily sour. I agree the op should keep an eye on this chick. You never know how each individual will be even with all other factors being the same.
In the first two days of the chick's illness she ate and drank and pooped. On the last morning when she refused to eat and drink she also didn't poop as far as I could tell for the 5-6 hours we observed her.
The crop didn't feel like it had anything hard or fibrous in it. The skin on her torso on the right side was flushed very red that day.
Would an impacted crop inhibit breathing? Whatever that substance was it was bubble filled, not as bubbly as cappuccino froth, but far more than bubbles in a carbonated beverage. Was in in her respiratory system or digestive system? I just don't know...
