I'm on day 21 of incubating eggs under a broody hen. Only 1 has hatched so far and that was earlier this morning. I have 7 other eggs which haven't even pipped yet. How can I tell if they're still gonna hatch or if I should throw them out, other than candling them/the water test because both of these methods said one egg wasn't rotten but it turned out it was. Any help is appreciated. Thank you.
