My hen has been laying on her 5 eggs for a while. On day 21, she had 4 eggs hatch, but one of them died. She stopped laying on the other egg for a few days now. Flies were all over the egg, and it was cold! I thought that it was rotten, so when I went to bury the egg, I cracked it open. There was a chick in it that looked pretty much developed, except for it's eyes, and it had some yolk outside. It wasn't moving at all, or making any sounds. Was I the cause of the death? The egg was cold. I was just wondering if I left it for a few more days, would it have hatched? I feel horrible right now
