I scanned most of the posts but didn't read all the replies so if I repeat something then I apologize.
I did notice you got a lot of advice on weaning so I'll skip that.
I don't have any experience with African grays so I don't know specific ages or weights but the good news is that specifics vary from bird to bird so it doesn't matter very much. It is all relative.
You need a scale that weighs in grams if at all possible. Most of the time it is recommended that your bird get about 10% of his weight in food per feeding so that can give you an idea of what he might need. Then you figure out how long it takes for his crop to be almost empty and that is when you need to feed him again. Probably about 4 times a day (maybe three).
Also you need to weigh him. If you weigh him before and after you feed him you can do the math and know how much he ate. This isn't critical to know but it can be helpful if you track it, it makes it easy to spot changes.
Weigh him at least once a day, I weigh mine first thing in the morning before the first feeding. He should be gaining weight each day until right before weaning. Since he has all his feathers he may be close to his top weight and my lose a little weight trying to prepare for flight. Has he flown yet. If not make his space safe for learning to fly because that will come soon. When my babies are learning to fly they are usually being fed formula three times a day and given solid foods to play with and try to eat in their cage. They will learn to eat the solid foods on their own.
While using a spoon or a syringe is better for the bird he will need to get used to the change and if he does not eat and loses weight you will have to use the tube feeding method just to keep him healthy. If he does not swallow the formula then don't add more to his mouth until it is out. Overwhelming him with formula can cause aspiration which can lead to death so you do have to be careful. Keep trying the spoon or the syringe but make sue he is eating even if he needs to be tube fed. Babies need to learn to eat and if you change the method it can take time for them to catch on so keep trying but never underfeed during a transition.
These are just a few thoughts. I hope they help.
