My maran Ling's crop started out big and squishy. We started puking her (stinky!) and feeding her yogurt and keeping her inside. Then, it turned small and hard like a golf ball, so we figured it must have become impacted, and we started giving her oil and massaging it. This lasted about two days. This morning it was no longer hard; it is big and soft. Is this a good thing? Does that mean the impaction is gone? I tried puking her but couldn't get anything up.
