I have three parrots, a TAG that I have had since she was 4 months old. Ana Grey is now 4 years old. Then I got my ZON, Louie, who was 2 when I got him and is now 4 years old. And finally my CAG, Sterling Gris, who I have had since he was 5 months old and is now 1 year old. Ana Grey, the smallest of my parrots and the first is the aggressive one in the flock. She is fearless but is the very close to me so will do as I ask with a little coaching and lots of persistence. My three jockey for position all the time and do fight and get in scraps a lot. They are out all day long and are all flighted so even though they do not like each other, they can each stand their ground and "make a getaway" if need be. Will they ever be "good buddies"???? Probably not, but I am retired so can watch them very closely. Do they challenge each other, of course, that's the way of the grey and the zon.
