I had cockatiels for years, once the pair figured everything out about 3 years old all they wanted to do is raise babies-they were such great parents. I let them raise them and I played with them and they turned out just as sweet as their handfed parents-some breeders wont agree with that but maybe it was because I had plenty of time and only a few birds. Congrats but be careful you can be up to your neck in cockatiels in no time lol
