Hi Tom, These are all questions we examine after any loss in case there are any lessons that can be learned. The first trimester of embryo development is the most precarious. This is often when mortality is seen in developing bird eggs. There are a variety of reasons including genetics, improper temperatures and humidity. First time couples are often inadequate at incubating. They may not cover the eggs completely or not properly relieve each other of incubating duties, leaving the eggs alone too often. If the egs are properly incubated from a young, genetically healthy couple; generally the embryos have protection from bacteria while in the egg shell. Bird eggs, including penguins, are best incubated by their parents. Their brood patch and burrow provide the proper protection and environment for success in hatching. Incubation is something couples become better at after a few times nesting.-Pamela Schaller

Hi Lynn, The audio is available during the 10:30am and 3:00pm feeds. It should come up automatically if you are watching the Cams during those times. Try htting the refresh button on your computer while watching.-Pamela Schaller

How do I get the Feeding Time audio? I can’t find a link.

Is it possible to prevent bacterial infections in the developing embryo? Can the source or cause of infection be determined? Do bird eggs have any natural protections against infection? Would a longer incubation period outside the nest, under more sterile conditions, be beneficial? Are egg infections common in other bird species? How will a future egg be more successful in overcoming infection?

They seem to be a caring couple. We appreciate you sharing this experience with all of us and look forward to a new clutch soon!

Definately a hard decision to make. So sad to hear they did not make it past the first tri-mester. Hopefully a second clutch will bring better results. Tony
