Well, I've been trying to mix pellets in with the seed for a little more than a week, hoping they might eat them accidentally.
When I put fresh food in yesterday, I did a couple dishes with mostly pellets and only a few oats/groats seeds...since they're bigger. Lily seems to be my adventurous one...excuse the rear view, but here he is chowing down!
Now I can only hope he's eating the pellets! Maybe my other keets will follow suit!
