Blue and gold macaw birds

Blue and gold macaw birds 2 years old ive had them for 2 years, male and female, wings are clipped, beak well trimmed, does NOT pluck, you can tell right off their eyes. They are a healthy bird eats parrot food (seeds & nuts) and tons of fruits and veggies..they are a HUGE chatter box picks up mostly any noise around them and ive have never met such birds that loves music the way they does! They are a little bit tamed and would let you hand feed them, pet them all around but they still doesn't know how to "step up" every time i try to teach them they just puts their head down to be petted! although the female is a bit shy around strangers, im re homing her because im super busy with work . These birds require a lot of attention and because im never home nor nobody is home anymore she has been spending most of her time alone and i know the lack of attention may cause the parrot to become stressed and have a change in behavior and might start to pluck so im trying to prevent that and give her away to someone who has time for her.
