Okay, my mistake then... I put the nest in her cage and now I guess I should take it out? She hatched somewhere around December 2010, so almost a year and 3 months. And about the calcium.... She won't touch a single one of the mineral blocks nor cuttlebones! Only her brother does. So, are there any other calcium sources for birds? I mean, I know fruits and stuff are great, but I don't know how she'll eat the CALCIUM stuff that I provided her with. Her name is Murphy (Ha ha) so I don't know if I should keep calling her that or not. But, I have a female Mama cat named Toby, who, again, was told as a male, and is actually a female. And I'm stuck with Murphy. I'll keep it Murphy, and then everyone will see that I'm clearly bad with genders. Ha ha
Is there a reason you are providing her with extra calcium or minerals? Is she deficient? If not, then a balanced diet* will provide her with what she needs! The only exception is if she is laying eggs-- she may well need more calcium then.
It's sort of an old fashioned approach to always provide calcium and mineral blocks to caged parrots and actually stems from research done on chickens. Back, many decades ago, the only research into domestic birds was done on chickens-- because chickens are a utility bird and thus the money was spent on research into them.That knowledge was then applied to the parrot world-- keeping parrots commonly in the household as a pet is a fairly recent trend as compared to keeping chickens-- and actually published in many parrot-raising books. This information was an okay basis and better than nothing, but ground dwelling galliformes (chickens) have much different nutritional requirements than most of our parrots do.
A balanced diet for cockatiels is no more than 40% seed, with the rest being veggies, cooked or sprouted legumes, etc. Fruit is okay too in small amounts but it's high in sugar. Here's some reading http://www.rationalparrot.com/diet.html
