Michael, my OWA was and is terrified of sticks. She was so bad she even made my BFA think he should be scared of a stick, and he had stepped up on a stick for years.hought about trying T stick...though I'm not a fan of them. Made one, but get anywhere close to cage he sees it and goes into squealing mode even several feet away.
She was not a biter but I wanted to have a non-flesh option when she was new, then I needed it for a male hormonal BFA.
What I did was use a bottom grate out of a small discarded prevuehendrix cage. I now find that the shelf from an old kitchen size freezer works great and is both small enough and large enough to be reasonable. Closet shelf grates from Home Depot look about the same and would work if you wife objects to your raiding the freezer.
They are not usually scared of grate design because it looks like their cage and they are not able to make a fast run across it to your hand if they are a bird inclined to do so.
Be aware to anchor the end before they step off it or it will rebound and hit them in the butt!
I use it once every day even if I don't need it, just to keep the option fresh.
