I have a chicken with that problem. I have to file my Took's nails and beak. I have someone turn him over on his back cause for some reason he seems calmer that way and I use a dremel with a sander on it and just sand his bottom beak til it's even with the top one. Plus it doesn't hurt that I talk to him. The nails are different though. I just hold one toe at a time and use my fingernail as a guide and just use the same tool and file until I reach my fingernail. He don't seem to mind.
