I have a question. A lady I met gave me some almost ready to hatch eggs. She doesnt know exactly when they are going to hatch. She had them inside of a coop and a hen was sitting on them. But she is about to move so she gave them to me. I candled them and they are full and appear to be about ready to hatch. So i brought them straight home and put them in the incubator. They smell though. I have them inside of my house and they have a foul smell. Is this a bad sign? Or could it be because they were in a coop before with chickens? I have never incubated before so I am not sure if it is just normal. There are 15 eggs and I would hate to toss them if they will hatch.
