My white Plymouth Rock has sour crop and I need to find a way to empty her crop without using the vomiting method. Iv'e never done that before and don't want to risk having her in hail the nasty stuff. She has had sour crop before and her crop eventually drained. However, I just realized that her crop hangs low and it quickly fills back up again. This I'm pretty sure is called pendulous crop. I hope to solve that problem with a crop bra, but I need a way to drain all that nasty liquid out of her crop first. I have no aviary vets in my area so help is greatly appreciated. Thank you!
