How much should a Hahn's macaw eat daily?

I feel like my sun conure either eats like a truck or barely touches their food depending on the day. What's a normal amount? I free-feed pellets and offer fresh food twice a day. Am I doing this right?

Couldn't agree more. This has been my experience as well.

This is one of those topics where I think there genuinely is no right answer. Both sides have valid points.

You're clearly a caring bird owner — the fact you're asking for help shows that. Your bird is lucky to have you.
