Hello and welcome to the family, Mosfatal, glad you could join us and we look forward to hearing more stories about Vattoe Chico. Thats some name and he corrects you if you don't say the whole thing, that is so funny.
No one is going to jump on you for doing the handfeeding yourself, it appears you have plenty of experience, and that is all that matters.
I see you are a vet student, will you specialize in avian medicine perhaps, we could always use some more good ones.
I see from your avatar that you have a cage similar to mine, and if you want to post another picture of your grey in this thread please do so we have a good one to look at to admire him.
If you have any specific questions you would like to ask, please do so and we will try to answer as best as we can. Also read over the many threads here for lots of useful information.
