I was told by my vet that fruit and veggies should be treats. That 100% pellets would be ideal. She is an avian vet so I went from 30% pellets to 95%. The stool was firmer but within 6 days my male was twitching his wings every few sec. It started on day 4 or so but I thought I was imagining it. After going back to a mixed fresh diet the twitching stopped completely. It only took a couple days! I didnt see any odd behavior when they were fed lots of fresh things. They aren't on any medication either.
