You may be thinking "Breeding is natural isn't it?". Or
maybe one of your question would be, "What can possibly go wrong?".
I'm here to tell you, if you can think of it going wrong,
it's most likely a potential problem. Breeding cockatiels is often very
simple but sometimes it just doesn't succeed. Some things gone wrong are
preventable or correctable, others are not.
To begin with you may have no eggs at all. This may mean
that you have set up 2 males or 2 females instead of one of each, that the
conditions aren't triggering breeding, that the birds are too young, the
birds are too old, the birds are eating their eggs as they are laid, that
the birds aren't healthy, that they have been overbred, or that your hen
is actually incapable of laying eggs due to physical problems. On a rare
occassion, maybe your birds just don't want to have a family but still
enjoy the act of breeding.
The eggs you get may be "clear" -- infertile. This may mean
that your male is an amateur who doesn't know what to do, your hen is
agressive and won't allow him to mate, they don't like each other, you
have 2 hens set up (especially if there are a lot of eggs and they are
laid daily), the perches are loose so they can't make good contact while
mating, The birds might be too young, the birds may be too old, the birds
may not be healthy, the birds could have been overbred, your cock may be
infertile, you may need to clip the males toenails because they are
hurting the female which causes her to try to avoid him, the feathers
around the vent of one or both birds may be making it impossible for the
male to carry out his responsibilities, or your hen may be infertile.
You may get eggs that begin to develop but die before
hatching. This may be due to genetic problems with the chicks, too much
humidity, too little humidity, poor sitting or turning of the eggs by one
or both parents, an infection either transmitted from parent to chick
before the eggs were laid or picked up through the pores of the eggs, a
crack in the eggs, mishandling and allowing overheating or chilling during
candling, marking the egg with a toxic marker, overheating in the nestbox
in summer, cold weather in the winter, or a decline in comodities prices
in Japan *grin*. Sorry, that list was getting too depressing.
Your chicks may hatch and develop problems later. The
parents may not feed them, the parents may feed them the wrong stuff
(bedding, undigestible seed, bits of paper, droppings, etc.), they could
get stepped on and killed in the nest, they may refuse handfeeding, they
may develop slow crop or sour crop, they may develop spraddle leg, they
may have congenital deformities, they may pick up an infection, their
parents may pick them bald or even pick them to death, they may get
chilled, they may get overheated, or you may have handfeeding troubles
such as aspiration or crop burn.
You may have trouble weaning as they determinedly cling to
their dependence on that formula long after your schedule says that they
should be eating solid foods. They may die close to weaning age due to
some problem like Psittacosis, or Polyomavirus. They may not get enough
good bacteria to fight off potential problems such as yeast infections.
They may have problems with malabsorption.
You may have trouble selling the babies because the market
is glutted, because they aren't properly tamed, because you lack business
skills, because people who don't know better will buy inferior birds in
pretty mutations or birds offered at a cheaper price rather then your
healthy grey splits, or because you can't bear to actually part with the
little darlings.
You may have one or both of the parents die during
incubation or while raising the chicks. You may even have a bird who
becomes aggressive and injures its mate or its chicks.
I don't claim that this list is exhaustive. Some of this is
likely to happen on your first tries. Most of it is unlikely in future
attempts but each of these things has happened to one breeder or another.
There is no magic bullet that will ensure success. Good nutrition,
scrupulous sanitation, and wise choices of breeder birds will go a long
way. You may need to re-pair birds who don't produce fertile eggs
together, to ruthlessly cull birds who carry deformities or have bad
parenting skills, to wait patiently for birds to mature, to handfeed when
you'd rather parent-raise, and to spend a lot of time and money at the
vet's. Sometimes you will get good advice, you will discover the cause of
the problem, and correct it easily. Sometimes not. Just because its
natural doesn't meant that its fail-safe.
