My daughter's little showgirl chicken has been sitting on some eggs, it's been about 27 days now. I've read eggs normally only take 21 days. There's no bad smell from the eggs and she continues to sit on them as stubbornly as can be. How long should I let her continue to sit on them. Is it possible they are just slow to hatch? I've never hatched eggs before in any capacity so I'm a super newbie at this! I really hope they're still okay, my daughter was super stoked that her chicken was gonna be a mommy. Thanks all!
