Quarantine

All of the below is doubly important when dealing with young, or just weaned chicks that do not have fully developed immune systems.

Why Quarantine?
This is probably one of the most mis-understood necessities of owning
birds. When one is quarantining a bird or birds it is to protect the
old flock as well as the new. Each group of birds live in their own unique
environment, and have built up immunities to the germs (good and bad)
that they are exposed to daily. Regardless of where a new bird is
purchased from, or how impeccable the husbandry or the reputation of the
seller, quarantine should be regarded as a very necessary practice.
The new bird is crated and taken from its eco-system and placed in a
totally new environment with a multitude of germs (good and bad) that it
has never been exposed to. During this move to the new location some
stress will be experienced. This stress can be very minor or it can be a
major upset, depending on the nature of the bird, the difference in
environment and how the bird reacts to it. During this time of stress, the
birds immune system may become suppressed, and the bird may not be in as
good a physical shape as when it left it's home. If the bird is not
quarantined, it will be bombarded by millions of new germs and the immune
system will need to kick in and respond to all these new germs (good and
bad). With a compromised immune system the bird will not be able to
surmount a good response and may indeed fall victim to a germ that normally
would not be pathogenic (disease causing) in this bird in a different
situation.
The new bird now becomes ill and starts shedding vast amounts of this
now (new to him) pathogenic germ, and also starts shedding germs in vast
amounts that the bird brought with him from his old environment. We now
have millions of pathogens in the environment that the resident birds
are being exposed to. Some are new germs, and some are old that they had
immunities to, but the shear volume is more than they can handle. Now we
have old and new birds getting sick, and of course one believes this
disease came with the newest arrival.
Obviously, if any of the birds involved had an existing disease, the
consequences would be much worse.
Had this arrival been quarantined properly, his stress level would not
have been so great and his immune response would have been able to build up
to the smaller amounts of germs it was exposed to. After a gradual time of
small exposures, the immune system can build immunities at a much more
normal pace, and not become compromised. This gradual transition into a new
environment proves beneficial, and necessary to all the birds involved.
Germs don't read one-way signs.
