I'm so upset with myself. My eggs were 36 hours over due (I only had 2). I had really thought that they stopped developing around day 17 because when I candled them they didn't move and didn't seem to be growing. On day 22 1/2 I did the float test and they failed (or so I thought). I wanted to see when they died, so I opened them up. The first one was hard to figure out so I opened the second one and it was still alive. I'm so upset. It still had a huge yolk sack and didn't seem very big, but it was alive!! UGH. I don't understand what I did wrong. Maybe it's because my temps were a hair lower than they should have been so they developed slowly? I'm so sad. I feel awful and didn't sleep....I wish I just left them alone.
