I have in the past, ground the cuttle bones into powder form to sprinkle on there food, but it takes a little time, now I just use a knife and scrap some of the cuddle bone on there food or just toss the whole thing in the enclosure.
i have it in her travel carrier so she isnt in it much but i havent tried any other kindd
she was scared of it so i didnt think she even touched it until one day i came home and her beak was pink lol
