Hi everyone I'm Katie, and my fiance and I are taking in a 10 year old male Grey on September 3rd! his name is Paco and we are very excited! He is going to be joining our large family! Our newest addition my 9 month old beautiful baby boy, along with our 2 cats, 3 dogs, a bearded dragon, and a very spoiled 28 year old Blue and Gold Macaw Koko!! So I do have expierence with large birds/parrots and am more then aware or all the dos-donts and no nos.. there is one concern for me though. Our Macaw, isnt a flyer we also don't clip her wings only because she doesn't know how to fly... She stays on her cage but we never shut the door, day or night the cage stays open so she comes and goes as pleases. At one point in her lifetime I am aware the owner got. 2Nd Macaw, and they did not get along. That was maybe 10 years ago... Now our soon to be grey IS a flyer and has never had his wings clipped. But from what I'm told, they keep him in the cage with the door shut, qnd only let's him out for feedings which he will fly around. The grey grew up with his neighbor a umbrella cockatoo, which they said they've never showed any aggresion towards each other. I would like any and all advice on having a smooth transaction coming to my house where he will have a new neighbor, should I keep both the koko and paco locked up untill their comfortable seeing each other? I guess I won't really know how it'll go untill I bring him home! Thanks
