Newbie incubating question - I have two eggs that the shells are very dark/thick - I couldn't see anything at day 7 and at day 14 I can only see the air cell at the end. It looks to be a normal size in both eggs (similar to the other eggs in the incubator) but everything else is too dark to make out. Is the formation of the air cell a good sign? Or would that form even if the egg weren't viable?
Thanks in advance!
