Tastier version of calcivet?

[hucker]

I cannot get my Greys to take calcivet. They will not allow it directly into their beaks as the vet suggested. Putting it in water requires using huge quantities of it, which is way too expensive. Putting it onto anything tasty like fruit makes it taste so bad they won't touch it. Is there something tastier?

Well, you never want to put anything in water (generally)..What types of birds do you have again?
