That's what I am thinking. You could try a laxative flush, but if it can't go through then it will probably be of limited use. Here's the recipe anyways-
LAXATIVE SOLUTIONS
The following solutions or mixtures are recommended to flush the digestive system of toxic substances, most notably for treating birds exposed to botulism toxins.
Molasses Solution
Add one pint of molasses to 5 gallons of water
Offer the drinking solution free-choice to the affected birds for about four hours. Treat severely affected birds individually if they cannot drink. Return the birds to regular water after the treatment period.
As a supportive treatment for symptoms resulting from Cryptosporidia infection, often referred to as coronaviral enteritis, use:
One quart molasses in 20 gallons of water
Offer this solution free-choice for a period of up to 7-10 days. It is assumed that the molasses replaces certain minerals lost from diarrhea during the course of the infection.
Epsom Salt Solution
1 lb Epsom Salt per 15 lb feed
-or-
1 lb Epsom Salt per 5 gallons water for 1 day
Give the epson salt feed mixture as the sole feed source for a one day period. This feed can be used only if the birds are eating. If the birds are not eating, use the water solution. If the birds are unable to eat or drink by themselves, use individual treatment with:
1 teaspoon of Epsom Salt in 1 fl oz water
Place the solution in the crop of the affected bird. This same amount of solution will treat 5-8 quail or one chicken.
Castor Oil Therapy
Dose individual birds with .5 oz castor oil.
Unfortunately, if she has an obstruction somewhere other than the crop it will either break down on it's own or not. If not, then she will likely pass as a result. So sorry you are both going through this.
Good luck.
