I would agree with everything that blr said. Good advice!! I think your cage set up is very nice-I remember when my cage looked that "empty". LOL My cage is tall so the top half is full of stuff to play with and chew on. The bottom half is more clear for fluttering.
It also depends on how much your little guy will get out of the cage. Mine are out 4-6 hours a day so they get plenty of flappy time.
I agree that clipping is a personal choice. I had my guys wings clipped (actually did it myself) and kept them that way for some time. I haven't clipped them since the last flight feathers have started growing. So far, so good.
The pellets you got are ok, but about 1/2 way through using them, you may want to think about getting Harrisons (or at least a brand with no coloring). Start putting the non colored pellets in with the colored ones and slowly increase the non colored ones as you decrease and then run out of the colored ones.
Also, what size did you get? Many of the ones that say "parakeet" size, most are too big and you will find yourself crushing them. If you get Harrison's, go with the superfine. I clicked on the wrong link and ended up with 5 lbs of the fine size that I had to feed into the blender to make smaller! LOL
Personally, I like either silo dishes or smaller dishes for food as well as water. What I mainly use for pellets is I got some of the really cheap silo feeders from WalMart and I only use the dish part. They can eat from inside or outside of the cage.
I'm also not sure about the cleanliness issue of using the coconut shell for veggies. Is it coated on the inside? If moisture from the food can seep into the coconut I would worry about bacterial growth.
Tomorrow is the big day right??? I can't wait to see pictures.
