As a bird breeder, it's important to know the ins and outs of egg fertility. When it comes to budgie eggs, they can survive without being incubated for up to seven days. However, it's still crucial to provide them with proper care during this time period to increase their chances of hatching successfully. It's best to keep the temperature around 70-75 degrees Fahrenheit and ensure that the eggs are not exposed to any extreme conditions such as direct sunlight or drafts. By taking these precautions, you'll be giving your potential budgies the best chance at thriving in their new environment.
