I use Polly's perches in between trimmings. They are made of cement and are a little rough, but they don't break the skin or cause infections like sandpaper. I would call around to pet stores. The one I got Evie from will trim the nails for $2.00. It's well worth it. Otherwise and avian vet will do it. My avian vet will not touch a bird to trim the nails or beak unless they have had a check up in the last year. I wouldn’t suggest doing it yourself unless someone shows you how first.
