Sun Conure chicks hatch after an incubation period of approximately 23 to 27 days, emerging as tiny, helpless creatures that bear little resemblance to the brilliantly colored adults they will become. A freshly hatched Sun Conure weighs between 6 and 8 grams and is covered in sparse white down with closed eyes and disproportionately large feet. The chick's skin appears translucent and pinkish, and its movements are limited to feeble head bobbing and feeding responses when the beak area is stimulated. These first hours are a critical window during which the chick's survival depends entirely on appropriate thermal support and timely first nutrition.
In breeder-managed clutches where the parents are experienced and attentive, the hen will typically begin feeding the chick within several hours of hatching. The crop milk and partially digested food she provides deliver essential nutrients along with beneficial microflora that begin colonizing the chick's sterile digestive tract. Breeders should resist the urge to disturb the nest box excessively during this period, as stressed parents may abandon or injure their offspring. A brief visual check to confirm the chick is alive and that the hen is positioned over it is usually sufficient for the first twelve hours.
For hand-raised chicks, the first feeding should not occur until the yolk sac has been fully absorbed, which generally takes between eight and twelve hours after hatching. Attempting to feed before absorption is complete can overwhelm the digestive system and lead to yolk sac infection or crop stasis. When the time comes for the initial feeding, offer a very thin, well-mixed hand-feeding formula at approximately 104 to 106 degrees Fahrenheit. The volume should be minimal, just one or two drops delivered slowly via a small syringe, allowing the chick to establish its feeding reflex without risk of aspiration.
The brooder must be prepared and stabilized well before the anticipated hatch date. Temperatures should be maintained at 96 to 98 degrees Fahrenheit with relative humidity between 60 and 65 percent. A reliable digital thermometer and hygrometer placed at chick level provide the most accurate readings. Even a brief temperature drop below 94 degrees can cause hypothermia in a newborn Sun Conure, and overheating above 100 degrees is equally dangerous. Line the brooder with soft paper towels rather than particulate bedding to prevent the chick from ingesting foreign material during its earliest feeding attempts.
