IAs the others said, I would NEVER give supplements to my parrots without a vet recommending it because they need it. Just give him a variety of fruits, veggies & pellets.
Alfie has all sorts of different perches in and out of his cage. Java, manzanita, rope, 'calcium'/cuttlebone/mineral, 'bee pollen'. I make sure they are varied in shapes and sizes so his feet get a good workout 😄
Weirdly, Alfie has never chewed his perches- even the edible calcium/cuttlebone ones.
I use manzanita wood for his fave high perch, plus mine has a cage-width-wide pine perch (came with the cage and which I've replaced a few times), plus a cotton braided rope spiral swing, and an acrylic ring swing. They are all various thicknesses so he doesn't get foot fatigue.
(I'm sad to report he also had a rough concrete perch in the 90s [supposed to keep nails trimmed] but I've changed my position on those and removed them).
