A distinct and unpleasant odor emanating from a bird egg is often a telltale sign of its demise. The smell is commonly associated with a rotten or sulfurous scent, resulting from the decomposition of the embryo inside the egg. However, not all dead eggs will necessarily emit a noticeable odor, especially in the early stages of development.


Dead bird eggs may exhibit alterations in coloration compared to healthy eggs. The eggshell might appear darker or display patches of unusual pigmentation or spots. In some cases, the entire eggshell can take on a gray or dull appearance. However, it is crucial to consider that certain bird species naturally lay eggs with inherent variations in color. Therefore, it is important to be familiar with the typical appearance of the species in question to accurately assess whether the discoloration indicates a dead egg.

Changes in Texture

Visual and tactile inspection can reveal changes in texture that signify a dead egg. Upon examination, the eggshell might feel soft, slimy, or exhibit visible cracks or holes. In more severe cases, the shell may even collapse or feel mushy when gently pressed. These alterations in texture indicate the breakdown of the internal structures of the egg and further suggest its lack of viability.

It is important to note that the aforementioned signs are not definitive proof of a dead egg. Various factors, including the developmental stage and specific characteristics of the bird species, can influence these visual cues. Therefore, it is recommended to consider multiple indicators and consult reliable sources or experts for accurate determination.

How to Care for an Egg

Proper care is essential for the successful incubation of bird eggs. This section will discuss the key factors to consider: temperature, humidity, and incubation techniques.


Temperature plays a crucial role in the development of bird eggs, affecting the embryo’s growth and determining whether the egg will hatch or not. Here are some important points to keep in mind:

  • Temperature range: Most bird eggs require a consistent range of 99 to 102 degrees Fahrenheit (37 to 39 degrees Celsius) for successful incubation. Maintain this range throughout the incubation period.

  • Stability: Fluctuations or extreme temperatures can harm the developing embryo. Provide a stable temperature environment and use a reliable thermometer to monitor the incubator or nest’s temperature.


bird egg humidity

Proper humidity levels are vital for the development of bird eggs, keeping the eggshell moist and enabling gas exchange for the embryo. Consider the following points when managing humidity:

  • Ideal humidity: The ideal humidity level for incubating bird eggs varies depending on the species. Generally, maintain humidity between 40% to 60% to prevent moisture loss or excessive buildup.

  • Dehydration risks: Low humidity can cause the egg to lose too much moisture, leading to dehydration and potential embryo death. Monitor and adjust humidity levels accordingly.

  • Hygrometer: Use a hygrometer to measure and regulate humidity levels within the incubator or nest based on the specific requirements of the bird species.


Incubation provides suitable conditions for the development of bird eggs until they hatch. Consider the following information regarding incubation:
