I have 40 eggs in lock down. One has hatched and seems to be doing fine. All candled good at day 7 and 14. One more hatched with yolk still attached and has a hernia with 2 inches of intestines hanging from the umbilical area. A second hatched with no yolk visible but still has Intestines showing from the umbilical. One more has pipped tonight. Its day 21 and I'm not sure the good chick is not peck and pulling at the umbilicals.
