I'm new here and I joined the site to learn more about raising chickens. I recently acquired some hatching black & lavender Bantam Cochin eggs, along with some mixed breed eggs. The bantam eggs are on day 7 and the mixed are on day 6. My eggs are currently in a Little Giant Still Air incubator and the temperature stays at 99.5 Fahrenheit and the humidity relatively stays at 50%. I have been noticing that some eggs develop a "ring" with no obvious signs of veins. I have included a couple of photos to show the rings which I am describing from two different bantam eggs. Could anyone help me identify whether or not this is the "ring of death?"
