Keeping Track of Weight Gain

To keep track of weight changes, we recommend the use of the chick growth chart where the weight gain % can be noted daily. From hatchling to the developmental stage (characterized by the emergence of feathers), a 10% daily weight gain should be expected. Also, the chart can be a valuable tool to help your avian veterinarian assess the health status of your chick.

Record Weight, Growth and More:

• presence and strength of the feeding response
• crop motility activity
• daily health parameters monitored
• quantities fed & evaluation of caloric intake
• consistency of the formula fed to the chick
• adequacy and respect for feeding schedules
• “plateau” of daily weight gain, preliminary stages of weaning, downsizing and firming up of the crop

Parrot chick weight monitoring normal growth curve

• 10% daily weight gain (logarithmic growth phase) for neonates (day 3 after the lag stage 0-3 days after hatch) until they reach the plateau age.
• Plateau when feathers emerge from pin feathers.
• 10% weight loss in total (from highest weight recorded) until completely weaned.
• An increase in weight thereafter should be attributed to pectoral muscle weight gain (especially if harness-trained).
• Fledglings, until juvenile age is reached should be monitored for weight control every few days.

Proper handling of the chicks

• Pressure should never be applied to the crop, chest or abdomen. Note: the liver lies beneath the pectoral muscles that have not yet developed therefore hepatic hematoma (bruising of the liver) can result from pressure on this region of the body.
• Fledglings instinctively develop a sense of balance. Holding the hocks and securing the body with an opposing thumb position on top of the wings and scapulars will help prevent flailing and grasping with the nails due to a sense of loss of balance.
• The container used to weigh the chicks safely on the scale should be large enough to accommodate the size, weight, movement and activity of the particular chick as it matures. Anti-slippery mattresses or substrates should be used to prevent legs from splaying.
