CrazyChickLady7, those roosters are gorgeous! Yes, I do crack the eggs open after the hen has abandoned the nest. A year ago, my broody kicked an egg out, to attend to her 3 feisty chicks (2 female, one male), and I picked up the egg and carried it around, and it started to peep... Sadly, it just couldn't get out of the shell, so I took it to an avian expert who got it out of the shell for me for $22.00, but it died a day later-- gender unknown. We think it didn't get enough humidity at a crucial point near the end of hatch. It was sad. After the broody abandoned her eggs to care for my latest little chick, I cracked open the eggs. One had died about Day 7, and a 2d looked to have lived to about Day 13, when the egg was rolled out and cooled for about 3 hours. The membrane was very tough and dry, similar to the membrane you sometimes find around an orange. The third egg might have hatched, had the broody stayed on the nest longer; I'm not sure. It had a whole bunch of runny yolk in it, though, along with the chick. So sad. My friend opened the incubator eggs that didn't hatch (6 out of 7) and they all contained nearly fully formed chicks with a lot of fluid.... Someone suggested too much humidity in the incubator, but he explained how he had corrected for that, and she said that should have taken care of the humidity problem, but, still, they didn't hatch, and we don't know why. He got just the one cockerel, hatched exactly 21 days from the date the eggs were placed in it. He opened the unhatched eggs earlier than I would have-- about 48 hours after the one hatched. I would have waited 72, but he didn't see any movement. My broody abandoned her nest only 48 hours after the one cockerel hatched. I would have liked her to have stayed on the nest a full 72 hours. However, I heard no peeps from the remaining eggs and saw no signs of pipping, so I don't think they would have hatched.
