Hi Iso,
I've been looking and looking, and can't find the information you're looking for, darn it.
All I could find, is thst they should not be bred under 12 months of age (but that's no help at all.
Found a bit of info about them though...
"Breeding tips
A full breeding diet should be started about 1 month before the breeding season, and should include a large amount of live food, soft foods, green foods, and dry seeds. Red-cheeked and blue-breasted cordon bleus can be paired for breeding as early as 6 months of age, but the blue-capped cordon bleu should be at least 12 months old due to problems with younger birds and egg-binding. These birds make use of ample hiding opportunities, especially during breeding. Therefore a fairly well-planted aviary or spacious flight with plenty of seclusion will do nicely. Breeding birds should be limited to a single pair per flight/aviary for best results. Avoid placing other cordon bleu pairs in adjacent enclosures; the sight of conspecifics will distract the breeding pair. Provide half open nest boxes, wicker nests, and hanging wire baskets stuffed with brush for nesting. Birds tend to build their nests three to 7.5 feet (1-2.5m) off the ground. Coconut fiber, fine grass, moss, and pale or white feathers should be provided for nesting material. Make sure these materials are available throughout incubation, as pairs will often add feathers to the lining of the nest around the time the young hatch, and may even place a feather to provide privacy at the nest entrance.
Cordon Bleu Pair Cordon Bleus may engage in "sexual chasing" where the male pecks at and chases the female he is bonded to, especially if their courtship display is interrupted by another male. This is thought to occur in order to drive the hen away from the presence of possible rivals. In the courtship display, a male will hold a piece of nesting material (usually a long piece of grass or a white feather) in his beak; he will perch near the female with his tail angled toward her and sing while bobbing up-and-down and throwing his head back each time he rises. If the female is on the ground, the male may hop around her as he displays. Females may also mimic this courtship display. As long as the female is receptive, most courtship displays result in the female crouching and quivering her tail to solicit copulation; the male may peck at the hen's head (not in a harmful way) just before mounting her.
Ample live food (such as mealworms, waxworms, termites) is essential for breeding birds to successfully rear chicks. You may additionally provide "insectivore diets" and dried ant eggs. Once chicks hatch, dishes of insects (live and/or dried) will need to be refilled several times daily. If the birds sense a shortage of live food, they will abandon their young or toss their chicks from the nest. Absolutely no nest checks should be performed as these birds scare easily from the nest. Several stressors may increase the risk of premature fledging or nest/chick abandonment, including: nest checks or disturbances, sudden diet change, shortage of live food or rearing food, administration of medication. If premature fledging occurs, do not attempt to replace the fledged bird to the nest as this may result in the siblings fledging prematurely; instead, fit the enclosure with a small brooder under which the fledges can huddle to stay warm at night, or bring chicks indoors (to keep them warm) overnight and release them back into the aviary in the morning.
Chicks hatch with reddish skin and fawn colored down. Parents cease brooding the chicks around the 9th day of age, so it is important to keep the enclosure sufficiently warm during this time. Parents may encourage the chicks to fledge by withholding food and calling loudly from outside the nest. Once young fledge the nest, they tend not to return to it, even during the first few nights after fledging. Because young birds are especially susceptible to the cold and dampness, these birds should only be bred during the warmer months unless the aviary/flight can be heated and kept dry. Within a week of fledging, it may be possible to distinguish young males from females as the males tend to be marginally deeper blue. Nest hygiene is poor, so the spent nest should be removed after fledging, and the parents given an opportunity to build a fresh nest for the next brood. Juveniles should be left with the parents for 4 weeks before removing them to their own enclosure to ensure independence.
Red-cheeked cordon bleus may be quick to accept a new mate if necessary; blue-breasted cordon bleus are more reluctant. When not breeding, birds should be placed on an austerity diet consisting of dry seed, minimum greens, sprouted seed, and only a small quantity of live food or egg food.
Life Cycle
