When should I candle my eggs to ensure optimal development and viability during the incubation process? Is there a specific timeline that I should adhere to, and at what intervals is it most beneficial to perform this insightful examination? Given the various stages of embryonic growth, wouldn’t it be prudent to discern the appropriate moments to illuminate these developing eggs? Perhaps I should consider factors such as the type of poultry, the incubation temperature, and the varying durations of different breeds. Additionally, how does the ambient environment influence the success rate of hatching? Should I be monitoring the eggs daily, or are there particular milestones, such as days 7, 14, and 21, which require more rigorous inspection? Furthermore, what signs should I be looking for during each candling session, and how do these indications vary depending on the stage of development? Isn’t it crucial to approach this with both caution and curiosity?
