Interesting you said that about nutriberries Muse. Timber is, unfortunately, a nutriberry bird. I tried every worthwhile pellet and got a resounding "no way." He would eat the nutriberries so that is what he gets. He also gets a lot of other things, so they aren't the total of his diet. However, he hasn't been eating them well since I started the new batch. Very interesting to see someone else has similar concerns...
