I really, really, really highly suggest getting your bird used to some kind of a harness, whether it be a flight suit, an aviator harness, or even a feather tether (which would be my last choice). You
do need to start very young. I would start within the first week you bring your baby home, if the breeder won't start for you.
I do not suggest ever taking your bird outside (even if clipped) unless he's wearing a harness or is caged.
I have a flightsuit for Ollie, but I can't get it on her. We've had better luck with the aviator harness (
http://www.theparrotuniversity.com/aviator.php), which a lot of people recommend. As for when mother nature calls...you carry some wet wipes, or don't take them anywhere where people are stingy about a little bird poo! I would like to be able to get the flightsuit on her for certain occasions (visiting family at their houses, etc), but it's just not to be! The aviator seems much sturdier to me, so I feel safe taking her outside in it- not sure how I would feel about the flightsuit in that regard.
