White Dove squabs hatch after an incubation period of roughly 14 to 16 days, emerging as small, vulnerable creatures covered in sparse yellow down. Unlike precocial species that can move about almost immediately, dove squabs are altricial and entirely dependent on their parents or a human caregiver from the first moment of life. A newly hatched squab typically weighs between 10 and 15 grams and will appear disproportionately large-headed with closed eyes and limited mobility. The transition from egg to open air is a critical window, and the care decisions made during these initial hours have an outsized influence on the squab's chances of survival.
In a parent-raised nest, both the cock and the hen share incubation duties and will immediately begin producing crop milk to feed the newly hatched squab. Crop milk is a nutrient-dense secretion produced by the lining of the parent bird's crop, and it is the sole food source for dove squabs during their first days of life. This substance is rich in protein, fat, and immunoglobulins that help establish the squab's immune system. The parents will begin feeding within the first few hours after hatching, and disturbance of the nest during this period should be kept to an absolute minimum to avoid triggering abandonment.
For those hand-raising a White Dove squab, whether due to parental rejection, egg rescue, or breeding program protocols, the first feeding should not be attempted until the yolk sac has been fully absorbed. This process typically takes between eight and twelve hours after hatching. Offering formula before the yolk sac is absorbed can overwhelm the undeveloped digestive tract and lead to serious complications including yolk sac infection. During the waiting period, focus on ensuring the squab is warm, dry, and resting in a clean, padded container.
The brooder environment must be established and stable before the squab hatches or is placed into your care. Temperatures should be maintained between 95 and 100 degrees Fahrenheit, with humidity levels between 55 and 65 percent. A reliable digital thermometer and hygrometer placed at squab level, not at the top of the brooder, will give accurate readings of the conditions the bird is actually experiencing. Any drafts or temperature swings during these first hours can rapidly lead to hypothermia or hyperthermia, either of which can be fatal to a hatchling dove.
