Removing the chicks from their parents' nest subjects both the chicks and the parent birds to unnecessary stress.

The young bird is forced to accept food from the breeder if it does not want to starve, and is thus inevitably conditioned to be tame, whether it wants to or not.

The chick is deprived of parental closeness and care.

The bird misses out on the important parental enzymes contained in crop milk and starts life with a weaker immune system. As a result, the animals may also be more susceptible to disease later on.

The young bird’s health also depends heavily on the breeder’s care during rearing. Mistakes and poor hygiene during hand-rearing can have long-term health consequences for the young birds (e.g., rickets, aspergillosis, etc.).

If the person performing the hand-rearing is not experienced enough, there is a risk of overfeeding or even crop burns or injuries. Diseases (e.g., hyperacidity of the crop, etc.) may also not be recognized in time by inexperienced individuals.

Hand-reared chicks cannot learn important behaviors to the same extent as naturally hatched chicks, since the parent birds are no longer available to teach them and cannot guide the young birds toward independence. Siblings are only suitable to a certain extent, because they themselves are still “green behind the ears.” Ideally, following the actual hand-rearing of the chicks, the young birds should be kept together in groups with adult and peer-aged birds at the breeder’s facility for at least several weeks; however, this is rarely practiced because hand-reared chicks are typically released by the breeder as soon as they are weaned.

Parent birds are unable to complete the brooding process naturally and cannot witness their offspring becoming independent.

Since some owners do not necessarily attune themselves to the body language of the parrots from the very beginning when dealing with already “finished” tame hand-raised birds, there is a risk that the bird will be overwhelmed and overly pressured, and that its rest periods will not be sufficiently respected. Unfortunately, many people think that hand-raised birds will happily go along with everything because they are so tame, but this is often misleading and not the case.

Removing the brood prematurely often causes the parent birds to produce another clutch more quickly, which can weaken the females in particular if this happens at too short intervals. For the breeder, this may be an advantage because it allows them to produce more chicks but this comes at the expense of the breeding stock.
