According to herpetologists, many species of reptiles—including certain snakes and lizards—lay soft, leathery eggs rather than the hard shells people associate with chicken eggs. Depending on the species and environmental conditions, females may deposit dozens of eggs in a single clutch or choose hidden, warm, and undisturbed places where the eggs can develop safely. If a house has been vacant for an extended period, it may become an attractive shelter for wildlife seeking protection from predators and harsh weather.
At first glance, it can be difficult for an untrained observer to determine whether mysterious white objects are reptile eggs, bird eggs, or even something entirely different. Appearance alone is rarely enough to identify them accurately. For this reason, experts recommend avoiding direct contact until the source can be confirmed. Disturbing wildlife or their eggs may be unsafe and, in some regions, could also violate local wildlife protection laws.
