Don`t forget , add different perches I don`t even use the dowel perches that came with my cages I have natural wood ones the boys love to pick at the bark (wash/scrub with diluted mixture of water and bleach or vinager leave in the sun to dry) rope perches or boings are loved by all fids and can hang from top of cage down making easy access to the bottom , I use a whole newspaper to line the bottom as its easier for the boys to walk on , roll up a sheet at a time when needed its easy ..I also add a toy box on the bottom with lots of goodies they can dig through and throw out

and Quakers love to nest of a night to sleep as in the wild they do have nests to sleep in so add some sort of hut to sleep up high with a perch running along so enty can be made in and out easily..
I am exited for you I love setting up new cages (or love to re arrange my boys with new branches and stuff every now and then) and yes you can buy S.S coups for feeding instead of the plastic thats easily fixed and not too expensive..
Congratulations .. don`t forget to share a piccy when your done... BEST of LUCK...

I never use the little doors for feeding my feed dishes are not even where the little doors are so I don`t think thats a problem ..
