sun conure personality change.
We took our newly adopted sun conure to get his wings and nails trimmed at the vet 3 days ago. Since then his personality has totally change. He wwent from a sweet socail bird to not talking at all and biting. He gets very territorial when you go near his cage. He had been trimmed before and didn't seem different until the day after the vet. I am unsure what to do. Please help if you have any advice as I don't want to have to find him a new home.
