catjsykes,
Congratulations on bringing your new charges home! You have started out in the right direction with both birds, and the advice you have been given by Monica and others is so correct, but I will share with you some ideas that I have found to to work with a good portion of my flock, but not everyone. Foods to cockatiels and budgies are much like anything that conjures up good thoughts in people, and it really truly is as much of a social event for eating as it is a nutritional event. Over the past 3 years, I've noticed that my most "social" birds, which include Missy, Gizmo, Chirp, Suzie, & Shelly, as well as Lil'bit all seem to congregate in the kitchen area when we start cooking supper. Yes, it's a dangerous game when you have red hot burners going, with boiling pots of food and deep frying grease on the stove, but we are very, very careful to make them stay away from anything that could burn them, and while I do wish they would wait till food is ready, it's just not going to happen. Anyhow, the act of cooking food, the smells of human foods they all seem to like is enough to make them sit on the top of the china cabinet, and on the top of the refrigerator just like a bunch of vultures ready to pounce on the latest roadkill

Once the cooking is over and food is placed on the table, we provide them all opportunities to eat whatever we have on the table, and that can be anything from fried chicken, pork chops, fish, roast beef, potatoes, vegetables of various types, and rice, which is a staple item in our house since Emi is Japanese. Anyhow, they have their choice of what they want to eat, and while it might not be normal cockatiel fare in the wild, we try to diversify their diet as much as possible. Their bird room foods consist of a good seed mix which contains a LOT of huge sunflower seeds (3-D Cockatiel Diet) sold at most WalMarts, pellets by Lafeber, fresh baby bok-choy, whole wheat bread, captains wafers (now and then) and just about anything we eat. So far, I've not had any dietary problems, health problems with the kids w/r/t diet, and so forth. One difference between me and probably most people except Mfids is all my flock are cage-free and have their own room which is 16x14' plus they have full roam/range of our house. Nothing in our house is sacred, including our bedroom! Cappy, who was the next to last addition is a 9 + old hen who hates my wife, but yet if she's left alone in the den where she normally sits, she'll waddle down the hall to our bedroom where Emi is to have company, even tho she will not even let Emi come close to her

Each birdie has a personality that you have to accommodate over time and you learn each other just as you would a human. They just can't talk in human language, but they can and will tell you when something is not normal, or bothering them or when they need attention. You just have to grow with the flock, because YOU are part of the flock.
I'm sorry if I've rambled on too much... probably too many 'ritas this evening, but when it comes to discussing our kids, there is nothing more I like to do, and let others know my experiences so they might gain some knowledge from my experiences and events. It might not hurt to do some searching on this board on diet stuff.. I've posted several posts about what I've learned over time, and by asking questions, but the main thing I always try to drive home to anyone new to cockatiels is diet MUST be varied and not just pellets and seed mix. They will not live long on just that. Meat protein is almost essential to any warm blooded animal or mammal. Cockatiels diets in the wild also consist of bugs, which is where the meat protein comes from.
Ok.. I hush now
