Remove that blue perch.
1. it needs cleaning.
2. it is an abrassive perch. If you want to include a pedi-perch, get a hagen one (they are super cheap, only a couple of quid).
To point out, one of my girls has a close foot, and because the toes all go forwards, the back of her toe/ankles touch the surfaces she sits on. She ended up with red patches, the vet told me it was her weight.
I would seriously consider taking this bird, and maybe a buddy if there is one, and housing them separately in a cage with an adapted environment. Otherwise you will have to adapt the whole aviary.
@Ripshod - any thoughts on gender?
