Cockatiel Sex Change
jge...@access.k12.wv.us
I have a lutino approximately 4 years old which I inherited from
my daughter. When she purchased it, she was told it was sexed and
was a male. About a year and a half ago, "he" started laying eggs.
Since then, he/she has repeated egg laying about every 5 weeks. He/
she is very cranky during the time before and after, leaving very
little "good" time. I am also concerned that she is wearing down her
system. Suggestions appreciated.

If you take her to an avian vet, or even just give one a call, he/she
can give you a complete set of instructions. I hope sincerely that you will
do this, as advice over the net is not anywhere near so valuable. BTW, chronic
egglaying is common in cockatiels.
Have you been removing the eggs? Don't, because she then feels obligated to
replace them. The eggs can be left, as long as they're not broken, for a
couple of weeks. You might try buying some fake eggs and substituting them for
the real ones, if you prefer.
Again, please consult an avian vet...the expense is not usually outrageous,
and the peace of mind is invaluable.

SPEAKING OF SEX... A friend of mine asked me to post the following
question: Is there any evidence that the gender of a bird is NOT
determined at time of fertilization? Can gender be controlled by some
factor during incubation?? Any help would be appreciated.

in humans. The only difference is that while the human male has an X and
a Y chromosome and the female has 2 X chromosomes, in birds it is the
female that has two kinds of chromosomes and the male two of the same. In
birds they are referred to as W and Z chromosomes.

Females are ZW, males are ZZ, just the opposite of humans where males are
XY and females are XX.

captive birds, it is possible to confirm that males have two X's (or
whatever letter is assigned to the chromosome) and females have one X and
one Y (or W or Z, as they are called in birds). These visible mutations
(cinnamon, lutino, and pearl in cockatiels) are carried on the X
chromosome, and their appearance always corresponds with the sex of the
bird, depending on how they were inherited.
Although birds descended from reptiles, they have evolved differently.
Their physiology, anatomy, and social structure is very different. The
possibility for conditions to determine the gender of the chicks must not
be beneficial to avian species.
