Thanks for all the responses, reading and re-reading them
So today I went out and got the 5lb green tub of Lafeber's pellets. Then I also picked up ZuPreem's Sensible Seed mix-a 2lb bag. I bought a food container[/URL] to combine them and it's now mixed and sealed. We'll try this combo for now, still incorporating his current food in it during the transition. I'll also write down what I mixed and bring it into the vet and see what she thinks/would suggest adjusting.
He did try fresh mango and LOVED it! But, even on sale it's $1 each and I don't think they last once they've been cut, so I found some dehydrated mango on sale for $4, for an 8oz bag (only ingredient is organic mango). This will be a reward/treat, maybe once a day? He's also been getting 1-2 peanuts a day as a reward for training, (stepping without beaking). When the bag is finished I won't be buying more, since peanuts seem to be on the crap list, lol.
And then on a whim I picked up some fresh broccoli (on sale for $1 a crown, can't beat that). It was so funny watching him with it-I put a piece it on his playgym and he freaked, LOL. He ran to the other side and head bopped at it for a bit. Then he inched forward, then scurried back, a few times. Finally he figured out that he could get on a higher rope and approach it from above...then he felt comfortable enough to do a quick taste. He really likes it and is now carrying it around the playgym making little noises LOL. I am seriously in love with this bird
