Sadiemae, I have heard the best way to gain a bird's trust is to hand feed it special treats, just like you mentioned earlier. I have an umbrella cockatoo, and two of her favorite treats are chicken (cooked of course) and toast with a little peanut butter. She nibbles on ALOT of what we eat. Our breeder told us the only things she absolutely couldn't have were: chocolate,rhubarb,onion, and avocado. He said anything else was okay in moderation along with her daily seed mixture. Hope this helps a little!
