Yes, I would consider it a part of the symptoms due to the fact any food or water being taken in is unable to be processed normally. Although, it isn't common in quail to have crop issues, with UE it will show up.@007Sean I do have a questionThe crop issue-is that uncommon in Quail or would you consider that a symptom of UE as a result of inflammation/infection in the intestines (slowing of the digestive system)? (much like with chickens - crop issues are often a sign/symptom of an underlying condition or infection)
Ulcerative enteritis and Infectious bronchitis are the two commonly addressed issues with raising quail. Aspergillosis is sometimes a factor with quail and pheasants and chickens as well...but UE and IB are the most common ailments encountered with quail.
