Wolf, I understand that. This is my main source of research, however, I do look at other webpages.. more "legit" ones I guess you can call it. I do prefer looking at forums seeing how there are so many others in the world who own a parrot, so there's got to be one who's had whatever problem I have/will encounter with my own. But I do check multiple sources.
FeatherKaeru, thanks for the advice! I do have a batch of gloop in my freezer but I just haven't given him any yet. He doesn't seem to be interested in his own food right now, just the stuff from the syringe so I might have to try this out haha. However, I'm sure the formula has a little more nutrients for him than the gloop since the fruits and veggies are mostly water.
Pajarita, I know and I feel so terrible that I didn't catch this mistake myself. I thought if he were truly hungry, he would eat his own food but I guess I stuffed him up with too much water so he had no room for real food

Before he got sick, I have seen him eat from his bowl even after hand feeding him so I figured even if I didn't fill him up, he would fill himself up after. I just didn't want to feed him so much that he would start to puke or explode because his crop would get so big and full!
