We have a 2yr old RIR. Three days ago we noticed hrr comb a little purple. When we took her out to examine her, her crop was over extended with fluid/water. As I was palpating, she vomited most of it out. There wss nothing in it but water. We brought her inside and have been massaging several times a day with oil dribbled into hrr. There is never anything but water. Yesterday she ate some oilly scrambled egg, then when I picked her up she vomited fluid and the egg. She is not eating(much) she has diarrhea. Her crop doesn't seem to be emptying at all but there is NOTHING in it but fluid. Could it be impacted further back?
