We have a chick! I'm not sure if there are others under there. I only hear one, but she's good insulation, so I'm not sure if I'd hear the others. She's on 6 other eggs. How long should I wait to remove the remaining eggs (I suspect one that may have quit, but I wasn't sure enough to pull it last week).
Unless they smell or the hen leaves them and builds her nest somewhere else I would give them till day 25 or so, the cold weather could have been delaying the eggs a bit. Mama hen will let you know.
