I have a very old Nanday Conure who no matter how hard I try is strictly a seed eater. Thought I would try this, but after 2 weeks in the food dish, still won't touch it. Can't slight the product, though. It is probably the bird!
I have been using Avicakes for my parakeets for probably 20 years. They love them and stay healthy. I had one bird live to age 16! My one complaint is the product shrinks in size every year and gets more expensive. When I first started getting them they filled the package so thoroughly it was hard to open. No more.
My two parakeets are picky eaters and it's hard to find a treat they really like. They love these, and there is always serious competition over who gets the best spot when a new Avi-Cake appears in the cage.
