There are a couple of things that I am concerned about in my incubating eggs. One of my EE eggs has an obvious baby developing...and quite well it would appear, but the air cell is at the pointy end. These eggs were pretty abused in shipping so I assume it was damaged then, but it seems to have actually secured to the opposite end. Should I flip the egg over (I am using egg cartons) to give the baby a better chance? It is developing completely in the fat end of the egg. Next, I had two (Black Tailed White Japanese Bantams) that were not developing at all. I cracked them to see what was in there and one had the yolk broken, again, rough handling. Now, a couple of my developing EE eggs had a very dark apperance throughout the inside. Is it possible for an egg with the yolk broken to start developing a baby chick? I mean, the yolk is just their food source while in the egg, correct, and the little white bullseye is what turns into a baby? If so, do they have any chance at all of making it to hatch? And last, just a happy brag. 5 of my 8 BLRW have definite babies, 2 are not sure, and one is almost definite not. My lone Silkie has a baby and I actually saw what I am pretty sure was a heart beat (rythmic beating), so I am super excited over that one!!! I have a total of 25 assorted eggs and there was a lot of development throughout.
