UPDATE: I want to give an update on how Goose is doing. After days, and days, and DAYS of massages, extra syringed water, miconazole, stool softener, molasses and several other crop treatments we were getting nowhere. She had a doughy crop each morning, a large practically overflowing crop at roosting time and super watery diarrhea multiple times through the day and night. I started her on acidified copper sulfate 4 days ago and am relieved to report that her crop and stools are miraculously back to normal!
