Was this cockatiel hand fed or parent raised? How old the little one now?
While I'm not experienced with cockatiels, in my opinion that's a lot of weight to be dropped in less than a week.
I can see two options that would explain this: either the chick wasn't fully weaned and is still currently in the process of being self-suficient in terms of eating or the very recently weaned chick was sold too soon, wasn't confident enough and has regressed in terms of weaning due to the change of environment (new family, new home).
A little bit of weight loss and different fluctuations in weight are to be expected in actively weaning chicks, but after they get the hang of eating, there will be a steady weight gain that in time will stabilize.
It would be important to know if the chick is currently having trouble in eating the seed mix/pellets and other foods. In terms of seeds, spray millet is good for chicks to practice eating and so is canary and flax seed. If need be, the owner can also crack open a few sunflower seeds and offer them to the chick.
Egg food is vital in this stage, introducing other fresh foods would also be beneficial.
Depending on the chick's condition, additional hand feedings may be necessary.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
