| Work of Barrat Watson: #s 1,3, &5 hens All chicks fed a watery formula, hence a lack of weight Abramson would rather see. | ||||||
Mechanical incubation of eggs might be necessary if the hen cracks them. Move chicks to brooder upon hatching, let them dry, then touch the umbilicals with iodine. After a few hours, give cool boiled water, and feed every two hours with a hand feeding formula or mix. Feed from Day 1. At 3 weeks, they are banded, and placed in plastic cages at room temperature.
Feeding time becomes playtime, tug of war, flight practice and voice testing (loud noises). Wear earplugs, if necessary. Flight with crash landings and speech possible in 73 - 90 days. Feeding is 2-4 times a day now. On weaning at 3 months, they were moved to a aviary where they can play a lot. At 6 months, the only difference is the young have dark eyes.
Joanne Abramson says they probably can breed at 3-4 years old, perhaps as early as 2 1/2 years. Easiest of the large macaws to breed. Babies need a vast amount of care from parents or surrogate parents (humans).
Only the best stock should be bred. Captive-bred seem to be better breeders than wild caught. Discards from others, poor quality birds or birds bought cheaply, should give you concern. Sometimes a macaw from a couple in a small house with a new baby because of the loud noises is a good deal. Quarantine all new birds from your other birds. Joanne (in California) suggests an 8' x 12' x 8' high outside flight.The indoor portion is 4' x4' x8' high with the breeding box container in this area. Pet birds can evolve into breeders as a natural outcome.
B&Gs begin to perch at 55-60 days, fly at about 85-90 days, wean at 14- 16 weeks. Backs and sides of cages near the nest box should be shielded from human traffic. In the flight cage, there should be perches or ledges for the bird to sit on, hanging rings, larger branches, ladders to the floor from platforms, crocks to bathe in, an interesting place to live.
