Foods That Promote Weight Gain

[Tupelo]

My cockatoo is underweight, and has proven to be a very picky eater. She does like mashed sweet potatoes with palm oil, but gets bored with that from time to time. Aside from this she will eat bananas, raw carrots, almonds, apples, and her pellets. She also doesn't have much of an appetite, as she is chronically sick.

Aside from any suggestions, I was wondering if I could mix some flax meal into oatmeal, as she'll eat oats sometimes? I've heard to avoid seeds, but I've seen flax in treats for large birds before, so I'm a bit confused. Also, has anyone given their bird tofu?

How about shelled and/or unshelled nuts?

And...have you ever heard of any of these??

She likes her almonds, though it seems lately she'd rather crunch them up than actually eat them. I'm not sure what other nuts she may enjoy.

As to your links, I'm kind of intimidated by the idea of hand feeding her, though would consider it if absolutely necessary. She is often too anxious to be handled, though. Some of this is general anxiety, and some of this is because I don't live with her right now.

I wonder what else I could sneak palm oil into. She won't eat it when I toss it on her chopped vegetables, or with pasta.
