Hello, This is my first time hatching eggs. My husband bought me an incubator last week. I put 10 eggs in. I candled the eggs tonight (the seventh day) as the manual suggested. Six of the eggs looked like they were supposed to according to what I have read online, a small mass and red veiny trails. However two of the eggs looked clear, and two were really dark all over except an air pocket at the large end of the egg. My questions are, are the two clear eggs no good and should be discarded, or should I give them a few more days? And, what is with the dark eggs? Since I picked eggs out of my pen that could have been sitting there for several days, is it possible a few started to develop outside and thus are further along in their cycle? No hen was sitting on them but it has been hot. Thank you for any advice.
