BUDGERIGAR SOCIETYS

Breeding problems

Breeding difficulties arise for various reasons. Some chicks may die from diseases and attacks from adults. Other budgerigars (virtually always females) may fight over the nest box, attacking each other or a brood. Sometimes budgerigars (mainly males) are not interested in the opposite gender, and will not reproduce with them. Sometimes a flock setting—several pairs housed where they can see and hear each other—is necessary to stimulate breeding. Another problem may be the birds' beak being under lapped. This is where the lower mandible is above the upper mandible.

It is very important to realize that most health issues and physical abnormalities in budgerigars are genetic. Care should be taken that birds used for breeding are active, healthy, and unrelated. Budgerigars that are related or who have fatty tumours or other potentially genetic health problems should not be allowed to breed. Parasites (lice, mites, worms...) and pathogens (bacteria, fungi and viruses), are contagious and thus transmitted between individuals through either direct or indirect contact. Nestboxes should be cleaned between uses. Splay legs, a relatively common problem in baby budgerigars, results from a young budgerigars slipping repeatedly on the floor of a nestbox. It is easily avoided by placing a small quantity of a safe bedding or wood shavings in the bottom of the nestbox. Alternatively, several pieces of paper may be placed in the box for the female to chew into bedding.

Development

They develop feathers around 3 weeks of age. (One can often easily note the colour mutation of the individual birds at this point.) At this stage of the chicks' development, the male usually has begun to enter the nest to help his female in caring and feeding the chicks. Some budgerigar females, however, totally forbid the male from entering the nest and thus take the full responsibility of rearing the chicks until they fledge.

Depending on the size of the clutch and most particularly in the case of single mothers, it may then be wise to transfer a portion of the hatchlings (or best of the fertile eggs) to another pair. The foster pair must already be in breeding mode and thus either at the laying or incubating stages and/or rearing hatchlings.

As the chicks develop and grow feathers, they are able to be left on their own for longer and longer periods of time. By the fifth week, the chicks are strong enough that both parents will be comfortable in staying more and more out of the nest. The youngsters will stretch their wings to gain strength before they attempt to fly. They will also help defend the box from enemies mostly with their loud screeching. Young budgerigars typically fledge (leave the nest) around their fifth week of age and are usually completely weaned a week later. However, the age for fledging as well as weaning can vary slightly depending on whether it is the oldest, the youngest and/or the only surviving chick. Generally speaking, the oldest chick is the first to be weaned. But even though it is logically the last one to be weaned, the youngest chick is often weaned at a younger age than its older sibling(s). This can be a result of mimicking the actions of older siblings. Lone surviving chicks are often weaned at the youngest possible age as a result of having their parent's full attention and care.

Hand-reared Budgies may take slightly longer to wean than parent-raised chicks. Hand feeding is not routinely done with budgerigars, due to their small size, and the fact that young parent raised birds can be readily tamed
