Kili does need a nail trim. Do you have an Avian Vet check scheduled for your new friend, if so, the vet can give her the first trim for you. Her nails are grown out and if you clip a little too close, they can bleed profusely.
If you both feel confident enough, you can trim Kili's nails with a pair of large nail clippers and shape them with a nail file. Those nails are tough, human nail clippers may not be sturdy enough. I use a pair of nail clippers for small breed dogs for my U2. Have corn starch handy in case of bleeding.
After the initial trim, provide lots of perches of different textures and diameters. I would give her one pedi-perch, but in a place that she doesn't use it exclusively. Scratchy perches and pedi-perches can cause sore feet if used constantly. Normal activity and a good diet help to keep the nails filed down naturally.
