Severe Macaw chicks hatch after an incubation period of approximately 26 to 28 days, entering the world as small, virtually helpless creatures. A newly hatched chick weighs roughly 10 to 14 grams and is covered in sparse, pale down that offers almost no insulation. The eyes are sealed shut, the limbs are weak, and the chick is entirely reliant on its parents or a human caregiver to regulate its body temperature and provide nourishment. Despite their diminutive size at hatching, Severe Macaws are among the largest of the mini-macaw group, and their growth trajectory over the coming weeks will be substantial.
In parent-raised clutches, the hen typically begins feeding the first chick within several hours of hatching. The initial feedings consist of crop secretions rich in proteins, lipids, and beneficial microorganisms that begin populating the chick's sterile digestive tract. If you are hand-raising a Severe Macaw chick, the first feeding should be delayed until the yolk sac is fully absorbed, which generally takes between eight and twelve hours after the chick emerges from the shell. Attempting to feed before absorption is complete can overwhelm the digestive system and lead to crop stasis or bacterial infection.
The brooder must be prepared well before the anticipated hatch date. Temperatures inside the brooder should be held steady between 96 and 98 degrees Fahrenheit, with relative humidity maintained at 60 to 65 percent. Position the heat source so that the chick can move slightly toward or away from the warmest zone, though movement will be extremely limited in the first day. Line the floor of the brooder with soft, lint-free material such as clean paper towels, avoiding anything fibrous that the chick could ingest.
Close observation during the first 24 hours is essential. A healthy Severe Macaw chick will display a feeding response when the corners of its beak are gently touched, its skin will appear pinkish rather than pale or discolored, and its breathing will be quiet and unlabored. Any sign of gasping, persistent shivering despite adequate brooder temperature, or a distended abdomen should be treated as an emergency requiring immediate avian veterinary intervention.
