I find our Gracie has to drop one about every 15-20 mins.
You can train parrots fairly easy to poop on command..
it takes patience, but more importantly it takes a higher level of attention & awareness of your bird so you know when it will need to relieve itself.
Our Gracie will poop on command..
LOL! I ususally say, "You Gotta poop?" just before we put her Flightsuit...
and I hear a little tiny nasal exhale (LOL! the equivalent of a birdy grunt) from her as she does. Good Bird!!
Getting a FID used to wearing a Flightsuit or "birdy diaper" is a bit more difficult.
I'll be honest, it's usually most sucessful when started at a young age.
It can be quite the process. The suit can feel somewhat restrictive- especially to a creature that's never had an item of clothing on it.
Introductions should be slow... You don't want the bird feeling like you are fitting them for the inside of some funny shaped snake. ;)
Of course, it does all depend on the bird.
Some birds will fight the suit beak & claw...
of course you realize in that situation, most likely that bird will be attempting to amputate any of human appendages that seem bent on helping the suit win.
Sadly some bird never get used to the feel of the suit...
Others, like our WCP, seem to accept it's presence
gracefully (pardon the pun) after some initial disagreement with it.
BTW, Flight-suit use has time limits too.
With Grace, her poops aren't really huge and most of the time they are quite solid, so she can have her suit on for 4-5 hours before you need to remove the suit and change the liner pad. The bigger & messier the droppings, the more often you will need to
***Note if you want to try using a flightsuit, I'd like to point out a personal modification I've made for Gracie's suit in my BB photo section. It's an easy to make extra liquid-proof liner that I insert to help prevent any looser or watery droppings from soaking through the suit.
OH yes....
As cute as it is....it is
very unwise to sleep with a FID.
You can roll over & trap it, crushing or even accidently smothering it.....
More than one bird owner has made that tragic mistake.
