I just had a hen stop sitting on her eggs. She had issues one day where she sat on the wrong nest probably most of the day and it was cold. She’s been off and on them since then but yesterday I decided she had no interest and didn’t want to come back and I would stop making her. She had cracked one from stepping on it. Yesterday was day 20, so far it appears only one has survived, the cracked one!!! I took them inside and used hot hands under many layers of a flannel sheet because I don’t have a heating pad. I damped the edges of the sheet with some drips of water and also put in a cup of water. I put them in a rubber tub with a lamp. I checked the temp before putting in the eggs, it’s around 99 but is hard to maintain! I’m just hoping the little egg survives and hatches soon! I’ve seen other ways you can temporarily make an “incubator” that might work to hatch them if they are still alive!
