The vet told me to feed her as much as I can, he did not specify exactly how much or when, so I asked around BYC about these things and learned that I should be feeding 30ml of the 'Liquid Nutrition' every 6 - 8 hours. I'll confirm this with the vet when he opens tomorrow.
The vet gave me a syringe-dropper to feed her with. I found the drops from the dropper just rolled right off her beak, so I tried dipping her beak into the contents of a spoon. When I did this she opened her beak and allowed me to pour the mixture in little by little. When her mouth is full, she tips her head back, swallowing, and rubs her beak together. Then I dip her beak in the stuff again and repeat the process until the spoon is empty.
Thank you for your concern! I will make sure to crack down on that vet to give me some solid information.
That's 30ml per kilogram, so if she weighs 4.4 pounds, she woul get 60ml every 6-8 as long as her crop was clearing and she can sit or stand.
