Hi cowgirl lexi and welcome to pettalk! We had a parakeet for almost 8 years. Is Cookie hand tame?? One of the ways we got Azure to eat Fruits & Veggies and all those yummy things that are good for him, was to eat it ourselves and IGNORE him. (If it's something you don't care for, pretend that you are eating). Smack your lips a lot, say Mmmmmmmmmmmm, anything to get his attention. It may take a while, but eventually they get so curious they want to find out for themselves. I also started out with cheerios because that is something that they almost inevitably love. That helps to build confidence in you, and then you can move on to lettuce, carrots, purple cabbage, etc.

Another thing about lettuce that I found was that my birds really prefer Romaine (opposed to green leaf, iceberg etc.) and I washed it very thoroughly and left it very wet. Azure's first step towards lettuce was to "take a bath" in it. After that he always got excited to see lettuce.

I hope these tips help and your Cookie will be eating them soon.
