Male Blue Front Amazon for trade

I have 3 male Blue Fronts and wish to trade 1 for a female at least 4-5 years old. Female must be DNA'd. Sorry for that, but no proof of sex is what got me where I am with these guys. 2 of my males are breeders only, the oldest being 10, but both are big handsome devils and the other was a one time pet. He sings take me out to the ball game, (the whole song) and I've been working on the railroad, (most of the song, with just a few words improvized, which makes it even cuter) He is a Chaco, very large big bird and right now very hormonal. We moved from a cold climate to here and they think it's spring...
