OK, first of all, let me correct a misconception, no two year old ekkie gets depressed because he 'wants to become a breeder'. I don't know who told you that but whoever it was did not know anything about parrots or even birds in general. I am saying this not to scold you but because if you are going to go into keeping an amazon in the same frame of mind, it is not going to work out. Parrot-human relationships only work when the human puts out A LOT of work and time into them. Parrots are not dogs and making us happy is not part of their psychological make-up so it falls to us to gain their trust and love. And, when you are talking about a male amazon, we are not talking 'depressed and sad' when it doesn't work out with their human, we are talking 'mean and bitey'.
First thing you need to do is stop grabbing him with gloves. This is a complete no-no with birds, my dear. It's not only a flooding technique (which have been proven to backfire in the long run and no longer recommended), the only time their bodies get 'grabbed' is when a predator gets them and, as we all know, this doesn't have a happy ending. Second thing you need to do is make sure he is getting a good diet because zons are highly prone to obesity, high uric acid and fatty liver and all of these are caused by a diet too high in protein. An amazon diet should be low protein, low fat, high fiber and high moisture. I don't use or recommend pellets because I've done research for years and I have concluded that dried-up, processed ground up grains with man-made vitamins are not the best dietary option for captive birds. It's not only highly unnatural, most of them contain soy (which I don't feed to any of my animals) and, besides, nobody even knows what the nutritional values are because the labels never give you specific numbers or even ranges. I feed mine (I have 6 amazons) gloop for breakfast, accompanied by fresh produce, and a small, measured portion of a low protein, good quality seed mix (3 of them get only budgie mix and the other 3 get half budgie, half cockatiel). Amazons are great eaters and bathers, they are independent and tend to be perch potatoes so, as long as you feed them right and keep them at the right light schedule, they are, actually, quite low maintenance compared to other species of parrots. BUT the males can be extremely aggressive when overly hormonal so it's imperative that they are kept to a strict solar schedule with full exposure to dawn and dusk and that they get a lower protein diet during the resting season (winter) to avoid problems. An overly hormonal male amazon is a powerful, large, fearless pissed-off animal that will think nothing of flying to you and biting a chunk of your face so it's essential to avoid this at all costs.
You should get the bird DNA'd to know for a fact whether you have a male or a female because it's very useful information for the long haul. If the bird talks so much, it's most likely a girl because they are the ones that have large vocabularies, males do talk but they are birds of 'few words'
Now, you are going to have to put A LOT of work and time into this relationship because first impressions are very important to parrots and you gave him a bad one (the gloves and predatory grab). He won't do any of the work. They never do because there is no hard-wired natural inclination for parrots to please us and, if they perceive you as not trustworthy, it takes a lot of work to dispel this and convince them we really are so arm yourself of resolve and patience and do everything right because, if you don't, it won't work out, same as the ekkie did not work out. It's never 'them', it's always 'us'. Parrots are naturally affectionate and forgiving but they also have long memories and reach conclusions of their own and, in their minds, the fact that you got the wrong info from somebody is not relevant at all, all they know and all they take into consideration is what you do and what you don't do. The reasons make no never mind to them.
Keep him at a strict solar schedule with full exposure to dawn and dusk and sleep when it's night (think of the schedule the birds on the trees follow), allow him as much out of cage time as you can, the more hours he spends out of his cage, the better he will feel (nobody likes to be in jail, right?), feed him early in the morning and when the sun is going down to reproduce the times he would eat in the wild (pet parrots might be captive-bred but they are not domesticated so their needs are identical to the wild ones), don't grab him and don't put your hand in his cage, just open the door and walk away. If he doesn't come out, don't worry, he will. Talk (praise, praise, praise), sing, whistle and generally keep him company. Offer him a treat every now and then. Don't try to force-handle him, don't ask for anything and, when the time comes that you can ask (it might take days or it might take months), don't insist if he doesn't want to do it. Parrots don't react well to discipline, demands or impositions, you need to win them over and trick them into thinking they are doing what they want when, in reality, we are maneuvering them into it. It takes patience, persistence, consistency and mental agility to keep up with them and, when it comes to large, potentially dangerous birds like amazons, it's not only in their best interest but also in yours to do so.
