Okay, my broody has been setting on random eggs for (apparently) 21 days. She started out with 8, and due to cracks and my own mistakes ended up with 3. She steals all the other hens' eggs, so today I went out there to get the un-set eggs from her. I lifted her off the nest and was planning on candling the three she's setting so I took those, too. Keep in mind I didn't know it had already been 21 days. Sure enough, as I was putting one of her eggs in the egg basket I felt a crack, and upon closer inspection realized the shell was broken in a square shape, and I heard faint chirping. I put it back, realized the broken area had probably been on the side/top of how it was laying, and moved it again. On second thought, now I'm kicking myself because I know it's important for the egg to not get turned so the chick can orient itself. I really didn't know they had survived, much less that it was hatch day!!! All three eggs got left out from under her at some point while she was cramming the other hens' eggs under her, so I really didn't think they'd make it! Did I totally screw up??????
