EDUCATIONAL INCUBATION & HATCHING CHAT THREAD, w/ Sally Sunshine Shipped Eggs

Saddle Shaped and Rolling Air Cell Images​

Saddle shaped air cells are when one or both sides of the egg have a large dip in the air cell. A lot of times with saddle shaped cells the chick doesn't position correctly for hatching. Their feet can get stuck behind their head and "smoosh" the chick so it can't move. It can also force the yolk sack and everything else more north in the shell. Keep a close eye on these eggs and make sure to pencil mark air cell lines. They are very common in shipped eggs. Please see the rest of the notes section for information on turning these eggs correctly.

Rolling air cells are just what the name implies: bubbles of air that roll freely throughout the whole egg like a carpenter's level. Prognosis for these eggs is generally poor and sometimes they are scrambled also.

Someone should write a short article on assessing a clear eggs fertility after incubation. I feel it's a not exposed subject!

I'm going to add the awesome write up you did on the HAL HAL to the fertility list.

That's fine with me!

Blood Rings​

Blood rings are the decomposing blood vessels in an egg that has died fairly early on in incubation. Rather than staying attached to the embryo, they form a circle around the yolk that usually goes all the way around the egg. Causes of the egg dying include bacterial infection, rough handling, and nutritional deficiency in breeding stock.

Dead-in-shell Candling Images​

What people define as being "dead-in-shell" varies, but for this purpose we will use the definition provided by pasreform.com which is "All embryos that died after the start of yolk sac retraction into the abdominal cavity, therefore all embryonic mortality after approximately day 17.” Some use it to describe eggs that pip but do not hatch.

Eggs with Incomplete CAMs​

CAM (chorio-allantoic membrane) issues are often caused by improper or no turning especially through days 1--12. This is when the chorion and allantois are developing and eventually fuse, forming the chorio-allantois. See turning section of the notes for more information.
