So, we're pretty sure one of our ladies has an impacted crop. Her crop feels like a large round ball, and she's been vomiting occasionally. Fortunately, she is still laying, and acting normal, and we called a vet. Unfortunately, the soonest we can see her is in a week. Until then, what should we be doing to take care of her? And, while it might be the best solution for another chicken, our girls freak out if separated, so that's not something we can do.
