When annoyed, a cockatiel will sometimes hiss to show its anger, even
at its beloved owner.  To avoid this reaction, learn to read the body
language of your 'tiel.  Excessive egg laying in females can cause a
range of problems, including calcium deficiency.  Prone to Giardiasis,
psittacosis, and upper respiratory infections.  Dusty birds, may be a
concern for those with allergies.

Visually sexing baby cockatiels is virtually impossible until their first molt, and even then depending of your cockatiels
coloring, it may still be impossible to visual sex.  The only way to know for sure when they are very young is to do a DNA
sexing test.  We can do this test, at a cost of $25 to you.  We can offer a suggestion of what sex we think our babies are
but cannot be 100% sure that we will be accurate in our assumption.  

Here is a link to a general guideline other breeders use to visually sex their cockatiels and this may help you in choosing
a cockatiel should the sex be important to you -
