She's a beautiful bird! Stunning head color, and it's good to hear she 'took' to you. They tend to pick a person, so maybe she picked you

I am personally quite fond of amazons and the 'zon' personality, but they aren't for everyone. I grew up with 2 amazons (1 being a female DYH) who are now both in their 40's and have my rescue BFA who's around 16. If you 'know what you're getting into' they are wonderful birds who will be a lifelong companion. A couple zon specific points-
They hit sexual maturity between 4-6 years old, which can bring on a fairly significant change in behavior for around 6weeks-2months each year. Typically, their breeding season is in the late winter/early spring here in the US. Hormonal behavior affects some individuals more than others and can go one of 2 ways, you are either their object of affection, or they become abnormally aggressive. Both 'issues' are natural, temporary and can be managed relatively well with slight routine, handling and dietary modifications. Females specifically can lay infertile eggs, but not every female will. This can bring on a whole host of other problems, but can also be a relative non-issue depending on the individual bird. My moms female DYH is 45+ and has never laid an egg, and it isn't AS common in amazons as other parrot species.
Amazons tend to be 1 person birds, and they pick the person. Through PROPER TRAINING AND SOCIALIZATION, they can be friendly and tolerant with other people in the home, but they will always have their 'favored' human. Our BFA was *suppose* to be my bird, but he fell in love with my husband and is incredibly bonded to him. That said, I can still handle him, he still interacts/plays with me and while he prefers my husband, I'm his friend too

That is due to patience, persistence and training/socialization. Had we let him, he would be very aggressive towards me, but I put in the effort to have a friendly bird.
Amazons are NOT known for being cuddly birds. Some will accept cuddles, most will accept scritches, but there are some stubbornly independent zons who just hate being touched. They will step up, but you can't pet on them. That is dependent on the individual, and their bond with you, but don't ever expect a zon to be a velcro bird. Most are happy to just be near you and observing you whilst doing their own thing.
Finally, amazons do have a bad reputation for becoming overstimulated, and thus they become aggressive. As you do your research, this point WILL come up and WILL single out DYHs as one of the 'hot 3' amazons. In my experience, once you learn the signs they are reaching their mental overload point, you can ABSOLUTELY avoid/prevent this issue 99.9999% of the time. It just takes being observant. IMO, amazon 'rages' are typically an unobservant owner problem rather than a species problem. All it takes is to distract your bird with a positive, focused activity (a toy, foraging, food) BEFORE they go over that edge.
Edit: Saw you already own birds, so you know the costs, noise, mess and biting stuff already

If you're a bird person, you would probably enjoy adding a zon to your flock! Great, hilarious, intelligent, independent, (relatively, by comparison to macaws and toos) low maintenance large parrot. Best of luck!
