One of my hens is sitting on a now very small clutch of eggs. Today is day 21...and I don't see anything happening. I never candled them, as it never seemed to be dark enough, and I just didn't know how to do it. They all smell stinky, but that could be because other eggs broke near them. How much hope can I still keep? I'm just ready to cry- we were really looking forward to some babies...and I fear that there will be nothing. And if they are all duds, what will happen to my broody? Does she know? Will she stop sitting on them? I just don't know what to do...
