It's worth a try, however this bird definitely has a fungal infection going on somewhere in her body. I have seen this same green diarrhea in birds with slow and sour crops. Her crop is not slow nor is it sour and nothing is impacted. This is why I am so confused with this. Green diarrhea can be some sort of internal cancer which I am starting to think is going on and this fungal infection is from her weakened immune system.Leyla, I would try the corrid. sounds just like mine were. I used 1 1/2 teaspoon per gallon of water for 5 days I think it was. they were bones. they are putting the weight back on fast but i have been cooking for them. tons of eggs with oats and cornmeal then what ever i had extra, greens, chicken strips.
I too am cooking extras for her and she eats fairly well but the weight is still coming off of her.
