A leopard gecko hatchling emerges from its egg after an incubation period of roughly 35 to 90 days, depending on the temperature maintained during development. The tiny gecko will typically measure between three and four inches in total length and may still have remnants of egg material clinging to its body. Allow the hatchling to dry naturally in the incubator before transferring it to a prepared enclosure. Avoid handling the gecko during this critical window unless absolutely necessary, as the stress of being moved is already considerable.
During the first day, the hatchling will rely on the remaining yolk sac nutrients it absorbed just before hatching. Do not expect the gecko to eat within the first 24 hours, as this is entirely normal behavior. Focus instead on ensuring that the enclosure is properly set up with a warm side, a cool side, and adequate humidity. A shallow water dish with clean, dechlorinated water should be available at all times, though the hatchling may not drink visibly right away.
Observe the gecko carefully for any signs of distress, such as labored breathing, an inability to move, or a visibly unabsorbed yolk sac protruding from the belly. A small amount of residual yolk material near the vent area is common and usually resolves on its own within a day. If the yolk sac appears large, inflamed, or is dragging on the substrate, consult a reptile veterinarian promptly. The first day sets the foundation for the gecko's overall health trajectory, so a calm and stable environment is essential.
