The lights are not working in the barn, and that evening I was late to chores so it was pitch black outside. I was using a flashlight, but I really only noticed it because of the smell.
Goat bile is really hard to miss.
I consulted Google, which can really be a hit or miss. The most likely cause is that she ate something poisonous, due to the violence and the suddenness of the puking. I didn’t realize until later that they’d found a way into the backyard and tasted the rhododendrons (which resulted in a more severe case later). Thankfully, she only had a few nibbles.
The biggest worry was that she wouldn’t stop puking, and I’d need to start worrying about dehydration and pumping her full of vitamins. Which, of course, couldn’t be oral, because they’d just vomit it all back up.
Thankfully, she stopped puking by that morning. Rancid bile covered the walls and most of her companions, but she wasn’t puking, and half-heartedly ate some alfalfa and grain.
Cleaning up all that was a joy.
But mostly I’m just really relieved it wasn’t going to turn into a long-term problem. A few days later, and she acts like it never happened.
