My cockatiels have been eating this for years and I've had good results. It's a sunflower -free mix and has a nice range of various other seeds.
Mixed with a good all around pelleted food and supplemented with fresh fruit and veggies,this does the trick.
It can be a tad pricey and difficult to find.
My birds have thrived on this for many years.

Pros: good balanced seed mixture; sunflower seed free

Cons: hard to find; price is a little high

i guess my boys are like kids if it is good for them they won't eat it. i don't know why maybe it is the taste but they won't tell me

Pros: good things in it

Cons: won't eat it
