Someone experienced with birds will be able to towel a bird to do a nail trim. My groomer is terrific with Dorian. For her nail and beak trims are a two person job, one holds the towelled bird, one does the trimming, then I come in and rescue him from the bad ladies lol. Believe me, he's trying his best to bite them during this process. Is there a bird club in your area. Contact a member and ask them who they use. I found mine by asking in a pet store that has a resident, and aggressive, amazon. Knocking him out is just too risky IMHO.
