Our female is somewhat "disabled" she had splay leg as a chick and had little braces on her legs (kinda like Forrest Gump!! ), when the vet was either putting a brace on or off, he broke one of her toes and it heal badly where her nail would grow directly into her toe. The vet removed that nail (and the first bit of her toe), I was so worried before having that done to her, about if I was making the right choice. But after seeing how well she does now and how much pain she must have been in, I know we made the right choice.
Well anyway, she is a LOT clumsier than our male, she does not wrap her feet around your finger or anything when she perches on you, where as he holds on so hard sometimes it hurts. Now she can grab on cause we do see her hanging or maybe dangling from her toys.
She falls a lot more often then he does, We took every precaution with her, but he does not have issues...
So I guess I am saying that it depends on the bird....But for a few weeks I definately would keep perches lower and maybe use a towel until you feel comfortable in their skills.
