Good broody hen, seemed happy...she still has 6 eggs under her on Day 22...yesterday we found 2 that had hatched, but to no avail...today, a beautiful hatch,seemed healthy, strong chipping...got all the way out of the shell, and then, 3 hours later, dead. Had a small little sack attached..to what looked like its belly? Ugh...any and all advice would be welcome, because we (or our Broody) are doing something wrong!) Thanks in advance, you all are great!!!
